Muenzaniso weMubvunzo weKukurukurirana weReagent Inoganhurira
Pendauluan
Mukemikari, imwe yepfungwa huru dzinowanzo kurukurwa ndeye reagent inoganhurira. Reagent inoganhurira ndiyo chikamu chiri mukuita kwemakemikari chinozotanga chashandiswa uye, nokudaro, chinosarudza huwandu hwechigadzirwa chinogona kugadzirwa. Kunzwisisa reagent inoganhurira kwakakosha nekuti kunotibatsira kufanotaura mhedzisiro yemaitiro emakemikari uye kushanda zvakanaka kwekushandiswa kwemakemikari muindasitiri kana murabhoritari.
Pfungwa yeKuganhurira Reagent
Mukutaura kunoshanda, chinhu chinodzivisa kudyiwa chinogona kuenzanisirwa kuburikidza nemuenzaniso. Ngatitii tinoda kugadzira masangweji nezvinhu zviviri zvikuru: chingwa nenyama. Kana tine zvidimbu gumi zvechingwa asi zvidimbu zvitatu zvenyama chete, tinogona kugadzira masangweji matatu chete. Muchiitiko ichi, nyama ndiyo chinhu chinodzivisa kudyiwa, kunyangwe paine chingwa chasara.
Panyaya yekemikari, pfungwa imwe chete inoshanda. Kana ma reactant maviri kana anopfuura achipindura, rimwe rawo rinotanga kupera, zvichideredza huwandu hwechigadzirwa chinogona kuumbwa. Iyi reactant inobva yanzi reagent inoganhurira.
Kuziva Reactant Inopera muKuita kweMakemikari
Kuti tizive reactant inogumira mukuita kwemakemikari, tinogona kushandisa matanho anotevera:
1. Nyora uye enzanisa makemikari equation yemhinduro.
2. Verenga huwandu hwemamota echinhu chimwe nechimwe chinowanikwa.
3. Shandisa stoichiometry (mole ratio) ye equation yakayerwa kuti uone huwandu hwechigadzirwa chinogadzirwa ne reactant yega yega kana chapera zvachose.
4. Tsvaga reactant inogadzira huwandu hushoma hwechigadzirwa. Iyi reactant ndiyo reactant inogumira.
Mibvunzo yemuenzaniso nekukurukurirana
Mubvunzo 1
Zvichitevera maitiro anotevera:
\[ 2 \text{H}_2 + \text{O}_2 \rightarrow 2 \text{H}_2\text{O} \]
Kana tikatanga kuita reaction nemamoles mashanu eH₂ nemamoles maviri eO₂, tsvaga reagent inogumira uye kuti mamoles mangani eH₂O achagadzirwa.
Kukurukurirana:
1. Nyora uye enzanisa maequations emakemikari:
\[ 2 \text{H}_2 + \text{O}_2 \rightarrow 2 \text{H}_2\text{O} \]
2. Verenga huwandu hwemamota echinhu chimwe nechimwe chinoita kuti munhu aite seanoda:
– \( \text{H}_2 \) = 5 mol
– \( \text{O}_2 \) = 2 mol
3. Shandisa stoichiometry kuti uone huwandu hwechigadzirwa chinogona kugadzirwa ne reactant yega yega:
– Kubva pa5 mol H₂:
\[ \text{Huwandu hweH₂O hunogona kuumbwa} = 5 \text{ mol H}_2 \times \frac{2 \text{ mol H}_2\text{O}}{2 \text{ mol H}_2} = 5 \text{ mol H}_2\text{O} \]
– Kubva pamamota maviri eO₂:
\[ \text{Huwandu hweH₂O hunogona kuumbwa} = 2 \text{ mol O}_2 \times \frac{2 \text{ mol H}_2\text{O}}{1 \text{ mol O}_2} = 4 \text{ mol H}_2\text{O} \]
4. Chinhu chinoita kuti chigadzirwa chisanyanya kugadzika ndicho \( \text{O}_2 \). Saka, \( \text{O}_2 \) ndicho chinhu chinomisa kugadzika, uye huwandu hweH₂O hunogona kugadzirwa i4 moles.
Mubvunzo 2
Zvichitevera maitiro anotevera:
\[ 4 \text{Al} + 3 \text{O}_2 \rightarrow 2 \text{Al}_2\text{O}_3 \]
Kana tikatanga nemamota masere eAl uye mamota mana e \( \text{O}_2 \), tsvaga reagent inogumira uye kuti mamota mangani e \( \text{Al}_2\text{O}_3 \) anogadzirwa.
Kukurukurirana:
1. Nyora uye enzanisa maequations emakemikari:
\[ 4 \text{Al} + 3 \text{O}_2 \rightarrow 2 \text{Al}_2\text{O}_3 \]
2. Verenga huwandu hwemamota echinhu chimwe nechimwe chinoita kuti munhu aite seanoda:
– \( \text{Al} \) = 8 mol
– \( \text{O}_2 \) = 4 mol
3. Shandisa stoichiometry kuti uone huwandu hwechigadzirwa chinogona kugadzirwa ne reactant yega yega:
- Kubva pamamota masere eAl:
\[ \text{Amount } \text{Al}_2\text{O}_3 \text{ inogona kuumbwa} = 8 \text{ mol Al} \times \frac{2 \text{ mol } \text{Al}_2\text{O}_3}{4 \text{ mol Al}} = 4 \text{ mol } \text{ Al}_2\text{O}_3 \]
– Kubva pamamota mana e \( \text{O}_2 \):
\[ \text{Amount } \text{Al}_2\text{O}_3 \text{ inogona kuumbwa} = 4 \text{ mol } \text{O}_2 \times \frac{2 \text{ mol } \text{Al}_2\text{O}_3}{3 \text{ mol } \text{O}_2} = 2.67 \text{ mol } \text{Al}_2\text{O}_3 \]
4. Chinhu chinoita kuti chigadzirwa chisanyanya kugadzikiswa ndi \( \text{O}_2 \). Saka, \( \text{O}_2 \) ndicho chinhu chinomisa reagent, uye huwandu hwe \( \text{Al}_2\text{O}_3 \) hunogona kugadzirwa i2.67 mol.
Mubvunzo 3
Zvichitevera maitiro anotevera:
\[ \text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3 \]
Kana tikatanga ne6 mol \( \text{N}_2 \) uye 18 mol \( \text{H}_2 \), tsvaga reagent inogumira uye kuti mangani mamoles e \( \text{NH}_3 \) anogadzirwa.
Kukurukurirana:
1. Nyora uye enzanisa maitiro emakemikari:
\[ \text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3 \]
2. Verenga huwandu hwemamota echinhu chimwe nechimwe chinoita kuti munhu aite seanoda:
– \( \text{N}_2 \) = 6 mol
– \( \text{H}_2 \) = 18 mol
3. Shandisa stoichiometry kuti uone huwandu hwechigadzirwa chinogona kugadzirwa ne reactant yega yega:
– Kubva pamamota matanhatu \( \text{N}_2 \):
\[ \text{Amount } \text{NH}_3 \text{ inogona kuumbwa} = 6 \text{ mol } \text{N}_2 \times \frac{2 \text{ mol } \text{NH}_3}{1 \text{ mol } \text{N}_2} = 12 \text{ mol } \text{NH}_3 \]
– Kubva pa18 mol \( \text{H}_2 \):
\[ \text{Amount } \text{NH}_3 \text{ inogona kuumbwa} = 18 \text{ mol } \text{H}_2 \times \frac{2 \text{ mol } \text{NH}_3}{3 \text{ mol } \text{H}_2} = 12 \text{ mol } \text{NH}_3 \]
4. Huwandu hwakanyanya hwechigadzirwa chinogadzirwa hwakafanana kubva kune ese ari maviri ma reactants, asi mudzidziso huwandu hunogumira hwechigadzirwa ndi \( \text{H}_2 \), saka \( \text{H}_2 \) inova iyo inogumira reactant.
Mhedziso
Pfungwa yekuganhurira reagent yakakosha pakunzwisisa maitiro emakemikari. Inobatsira kufanotaura mashandiro anoita reagent uye huwandu hwechigadzirwa chinogadzirwa. Mukushandiswa kwemaindasitiri, kunzwisisa nekuona mareagent anoderedza kwakakosha pakuvandudza mashandisirwo ezvinhu zvakachekwa uye kuderedza marara.
Muchinyorwa chino, mienzaniso yezvinetso nehurukuro zvinopihwa kubatsira vaverengi kunzwisisa matanho ekuona reagent inogumira. Nekudzidzira uye kunzwisisa kwakanaka, pfungwa iyi inogona kushandiswa kune akasiyana-siyana maitiro akaomarara emakemikari.
