Pendahuluan
He ariā taketake te pūngao here i roto i te matū me te ahupūngao e whakamārama ana i te taunekeneke a ngā ngota me ngā ngota. He mea nui te mārama ki te pūngao here hei mārama ki ngā tauhohenga matū, te pumau o ngā ngota, me ngā momo tukanga thermodynamic. Ka matapakihia e tēnei tuhinga te whakamāramatanga o te pūngao here, ōna momo, me te whakamahinga o tēnei ariā i roto i ngā tono pūtaiao me ngā tono ahumahi.
Te Whakamāramatanga o te Pūngao Here
Ko te pūngao here e tautuhia ana ko te pūngao e hiahiatia ana hei wawahi i te kotahi ira o ngā here i roto i te ngota, ka hua ake te hanganga o ngā ngota hau kore utu, koretake. Ina koa, ko te pūngao here he ine i te kaha o te here matū i roto i te ngota, i te katote rānei. Ko te teitei ake o te pūngao here, ko te kaha ake o te here, ā, ko te uaua ake hoki ki te wawahi.
Ko te pūngao here ka inehia i roto i ngā kilojoules mō ia mole (kJ/mol) me ngā electronvolts (eV) rānei, i runga i te horopaki me ngā hiahia tātari. Ka mahia ngā inenga pūngao here mā te whakamahi i ngā tikanga whakamātautau maha, tae atu ki te tirotiro ira me te ine karori.
Ngā Momo Pūngao Here
He rerekē ngā momo pūngao here, i runga i te momo here me ngā taunekeneke i waenga i ngā ngota, i ngā ngota rānei. Anei ētahi momo pūngao here e kitea whānuitia ana:
1. Pūngao Herenga Taurite:
– Ko te hononga honohono he hononga i hangaia e te takirua irahiko i waenganui i ngā ngota e rua. Ko te kaha o te hononga honohono e pā ana ki te kaha e hiahiatia ana hei motu i te hononga i roto i te ngota hau.
2. Pūngao Here Ā-Ionika:
– Ka hangaia ngā hononga katote mā roto i ngā taunekeneke hiko-pūmau i waenga i ngā katote pai (kationa) me ngā katote kino (aniona). Ko te pūngao hononga katote e whakaata ana i te pūngao e hiahiatia ana hei wehe i ēnei katote mai i tō rātou hanganga tioata ki ngā katote hau kore utu.
3. Pūngao Herenga Whakarewa:
– I roto i ngā hononga whakarewa, ka tohaina e ngā ngota he "moana" o ngā irahiko e nekeneke noa ana i waenga i ngā katote pai. Ko te pūngao e hiahiatia ana hei wawahi i ēnei hononga i roto i tētahi hanganga whakarewa e mōhiotia ana ko te pūngao hononga whakarewa.
4. Pūngao Herenga Hauwai:
– Ko te hononga hauwai te taunekeneke e puta ana i waenga i te ngota hauwai e herea ana ki tētahi ngota irahiko kore (pēnei i te hāora, te hauota rānei) me tētahi atu ngota irahiko kore. Ko te kaha hononga hauwai he ngoikore ake i ngā hononga irahiko, irahiko rānei, engari he mea nui ki te hanganga me te mahi a ngā koiora ngota, pērā i te DNA me ngā pūmua.
Pūngao Here me te Thermodynamics
I roto i te horopaki o te thermodynamics, he hononga tata te pūngao hononga ki ngā huringa pūngao i roto i ngā tauhohenga matū. Ko ngā tauhohenga exothermic, e tukuna ana te pūngao ki te taiao, ko te tikanga ka uru ki te hanganga o ngā hononga matū he kaha ake i ngā hononga kua motu. He rerekē, ko ngā tauhohenga endothermic me mimiti te pūngao, nā te mea he ngoikore ake ngā hononga i hangaia i ngā hononga kua motu.
Ko te matū wera he peka o te matū e ako ana i ngā huringa pūngao e haere tahi ana me ngā tauhohenga matū, tae atu ki te pūngao here. Ka taea te tatau i te enthalpy (ΔH) o tētahi tauhohenga mā te tango i te tapeke o ngā pūngao here i hangaia mai i te tapeke o ngā hononga i whati. Ko tētahi tātai māmā e whakamahia whānuitia ana ko:
ΔH = Σ (Pūngao o ngā Here i Whati) – Σ (Pūngao o ngā Here i Hangaia)
Pūngao Here me te Matawai
He taputapu nui te tirotiro irahiko mō te ine i ngā pūngao here. Ka whakamahia e tēnei tikanga te taunekeneke i waenga i te irahiko hikohiko me te matū hei tiki mōhiohio mō te hanganga me ngā pūngao here i roto i aua ngota.
He maha ngā wā ka whakamahia te mātakitaki irahiko (IR) me te mātakitaki irahiko Raman hei tautuhi i ngā pūngao wiri o ngā ngota, e pā tata ana ki ngā pūngao here. Ka taea e te mātakitaki irahiko ultraviolet (UV) me te mātakitaki e kitea ana te whakarato i ngā mōhiohio mō ngā whakawhiti hiko i roto i ngā ngota, tae atu ki ngā pūngao here i waenga i ngā ngota.
