Umehluko phakathi kokusabela kwe-endothermic kanye ne-exothermic
Isingeniso
Ukusabela kwamakhemikhali kuyizinqubo lapho ama-athomu nama-molecule ahlangana khona ukuze akhe izinto ezintsha. Lezi zinqubo zingenzeka ngezindlela ezahlukene, kuye ngokuthi ukushisa kukhiqizwa noma kudonswe ngesikhathi sokusabela. Kulesi sihloko sizokhuluma ngomehluko phakathi kokusabela kwe-endothermic kanye ne-exothermic.
ukusabela kwe-endothermic
Ukusabela kwe-Endothermic yilokho lapho ukushisa kuthathwa khona emvelweni ukwenza ukuphendula. Lokhu kusho ukuthi amandla emikhiqizo makhulu kunamandla ama-reactants. Ngakho-ke, ukusabela kwe-endothermic kudinga okokufaka kwamandla ukuze kuqaliswe.
Izibonelo zokusabela kwe-endothermic
- ukuncibilikisa usawoti emanzini
- iqhwa elincibilikayo
- I-Photosynthesis
Kuzo zonke lezi zimo, ukumuncwa ukushisa okuvela emvelweni kuyadingeka ukuze ukusabela kwamakhemikhali kwenzeke.
ukusabela exothermic
Ukusabela kwe-exothermic yilokho lapho ukushisa kukhishwa endaweni ezungezile ngesikhathi sokusabela. Kulokhu, amandla ama-reactants makhulu kunamandla wemikhiqizo, ngakho-ke ukushisa kukhishwa. Ukusabela kwe-exothermic akudingi umthombo wamandla wangaphandle ukuze kufezeke.
Izibonelo zokusabela kwe-exothermic
- Ukushiswa kukaphethiloli
- I-oxidation yezinsimbi
- Ukuvutshelwa
Kulezi zimo, ukukhululwa kokushisa kuyi-byproduct yokusabela kwamakhemikhali.
Isiphetho
Kafushane, ukusabela kwamakhemikhali kungaba endothermic noma exothermic kuye ngokuthi ukushisa kuyamuncwa noma kukhishwa ngesikhathi sokusabela. Ukusabela kwe-endothermic kubonakala ngokudinga umthombo wamandla wangaphandle, kuyilapho ukusabela kwe-exothermic kukhiqiza ukukhululwa kwamandla. Kubalulekile ukuqonda umehluko phakathi kwalezi zigaba ezimbili zokusabela kwamakhemikhali ukuze uqonde kangcono izinqubo eziningi kukhemistry kanye nokuphila kwansuku zonke ngokujwayelekile.
