Ngā Āhuatanga e Pā Ana ki te Taurite Matū
He āhuatanga nui te taurite matū i roto i ngā tauhohenga matū maha, i roto i te taiwhanga me te oranga o ia rā. Ka tutuki tēnei taurite ina ōrite te tere o te tauhohenga whakamua ki te tere o te tauhohenga whakamuri, me te noho pūmau tonu o ngā kukū o ngā matū tauhohenga me ngā hua. Ahakoa te āhua nei he āhuatanga pumau, ko te taurite matū he āhuatanga tonu e puta ana i te taumata ngota. Ka matapakihia e tēnei tuhinga ngā āhuatanga matua e pā ana ki te taurite matū, tae atu ki te kukū, te pēhanga, te rōrahi, te pāmahana, me ngā whakakorikori.
Te arotahi
Ina kōrerohia ngā tauhohenga matū, ko tētahi o ngā mea matua e pā ana ki te taurite ko te kukū o ngā matū tauhohe me ngā hua. E mea ana te mātāpono a Le Chatelier, mēnā ka puta he huringa o te kukū, ka whakatikatika te pūnaha i a ia anō kia whakahokia mai te taurite.
Hei tauira, i roto i tētahi tauhohenga hau e ōrite ana te kukū o ngā hau \(A\) me \(B\) ki ngā hau hua \(C\) me \(D\):
\[ aA + bB ⇌ cC + dD \]
Ki te piki ake te kukū o tētahi o ngā matū tauhohe, hei tauira, ko \(A\), ka urupare te pūnaha mā te neke i te taurite ki ngā hua hei whakaiti i tēnei raruraru. I tetahi atu taha, ki te heke te kukū o te hua \(D\), ka nekehia hoki e te pūnaha te taurite ki te taha matau hei whakaputa i ētahi atu \(D\).
Pēhanga me te Rōrahi
He mea nui te pēhanga me te rōrahi e pā ana ki te taurite i roto i ngā tauhohenga hau. E hono ana ēnei mā te Ture a Boyle, e kī ana ko te rōrahi o te hau he rite whakamuri ki tōna pēhanga i te pāmahana pumau. Ka pā ngā tauhohenga e uru ana ki ngā hau ki te pēhanga hau katoa i roto i te pūnaha, ā, ka pā pea ngā huringa o te pēhanga ki te ahunga o te taurite matū.
Hei tauira, me titiro tātou ki te tauhohenga e whai ake nei:
\[ N_2(g) + 3H_2(g) ⇌ 2NH_3(g) \]
I tēnei āhuatanga, e whā ngā ngota hau kei te taha maui, e rua kei te taha matau. Mēnā ka whakanuia te pēhanga i runga i tēnei pūnaha, ka neke te pūnaha i te huarahi e whakaiti ana i te maha o ngā ngota hau, i tēnei wā, ki te taha matau, ka whakanuia te hanga o te haukini (NH₃). I tētahi atu taha, ki te whakaitihia te pēhanga, ka neke te pūnaha ki te taha maui ki te whakanui ake i te maha o ngā ngota hau hei utu mō te huringa.
Suhu
Ko te pāmahana tētahi o ngā mea tino nui e pā ana ki te taurite matū. Ko te pānga o te pāmahana ki te taurite e whakawhirinaki ana ki te āhua wera-waho, wera-roto rānei o te tauhohenga. Ka rerekē te urupare a ngā tauhohenga wera-waho (tuku wera) me ngā wera-roto (mimiti wera) ki ngā huringa o te pāmahana.
Me kī tātou ka kite i te tauhohenga werawera e whai ake nei:
\[ 2SO_2(g) + O_2(g) ⇌ 2SO_3(g) + wera \]
Mā te pikinga o te pāmahana ka nekehia te taurite ki te taha maui (ka nui ake ngā matū tauhohe) i te mea ka ngana te pūnaha ki te mimiti i te wera nui. I tetahi atu taha, mā te hekenga o te pāmahana ka nekehia te taurite ki te taha matau (ka nui ake ngā hua).
Mō ngā tauhohenga endothermic pēnei i:
\[ N_2O_4(g) + wera ⇌ 2NO_2(g) \]
Mā te whakanui ake i te pāmahana ka nekehia te taurite ki te taha matau, ka nui ake te \(NO_2\), nā te mea ka mimiti te pūnaha i te pūngao wera. Nō reira, he mea nui kia mārama ki te pūngao wera e uru ana ki tētahi tauhohenga i te wā e tātarihia ana te taurite matū i ngā pāmahana rerekē.
Kaiwhakaoho
He matū te whakakorikori e whakanui ana i te tere o te tauhohenga, engari kāore e whai wāhi tonu ki te tauhohenga. I ētahi wā, kāore e mārama te pānga o ngā whakakorikori ki te taurite matū. Inaa, kāore ngā whakakorikori e neke i te tūranga taurite nā te mea kāore e pā ki ngā kukū whanaunga o ngā matū tauhohenga me ngā hua i te taurite.
Ko tā te whakakorikori he whakatere i te whakatutukitanga o te taurite mā te whakaheke i te pūngao whakahohe mō ngā ahunga whakamua me ngā ahunga whakamuri o te tauhohenga. Nō reira, he pai ngā whakakorikori i roto i ngā tauhohenga he mea nui te tere o te tauhohenga, pērā i te umanga matū, e arotauhia ai te wā whakaputa me te whai huatanga.
Te Whakamahinga o te Mātāpono a Le Chatelier i te Oranga o Ia Rā
E ai ki te Mātāpono a Le Chatelier, he maha ngā whakamahinga o te mārama ki ngā āhuatanga e pā ana ki te taurite matū, tae atu ki ngā tukanga hanga ahumahi, te whakahaere parahanga, tae noa ki te tinana tangata.
I roto i te umanga matū, ko tētahi o ngā tauira rongonui ko te tukanga Haber mō te hanga haukini, e whakamahia ana hei hanga maniua. Mā te mārama ki te pānga o ngā panonitanga o te pēhanga me te pāmahana ki te taurite i waenga i te hauota, te hauwai, me te haukini, ka taea e ngā kaihangarau te whakarerekē i ngā āhuatanga whakahaere kia nui ake ai te hanga haukini.
I roto i te whakahaere parahanga, ka whakamahia anō hoki tēnei mātāpono hei whakaiti i ngā tukunga hau kino. Hei tauira, i roto i te kaitahuri whakatere o te motuka, ka hurihia ngā waikura hauota hei hauota me te hāora i raro i te awe o te whakatere konukawata, palladium rānei. Ka āwhina te whakatere kia tere ake te eke ki te taurite e hiahiatia ana, ahakoa kāore e whakarerekē i te taurite tonu.
Whakamutunga
He mea nui te mārama ki te taurite matū me ngā āhuatanga e pā ana ki tēnei i roto i ngā momo mara o te pūtaiao me te ahumahi. He mea nui ngā āhuatanga matua pēnei i te kukū, te pēhanga, te rōrahi, te pāmahana, me ngā whakakorikori ki te whakatau i te ahunga me te tere o ngā tauhohenga matū ki te taurite. Mā te mātāpono a Le Chatelier ka whakaratohia he anga ariā e āhei ai tātou ki te matapae me pēhea te urupare a ngā pūnaha matū ki ngā āhuatanga taiao e huri haere ana. Mā te mārama ki ēnei mātāpono, ka taea e tātou te arotau i ngā tukanga matū maha hei whakatutuki i ngā putanga e hiahiatia ana, i runga i te tauine taiwhanga me ngā tautuhinga ahumahi nui, tae noa ki te oranga o ia rā.
