Umahluko phakathi kwe-endothermic kunye ne-exothermic reaction

Intshayelelo

Ukusabela kweekhemikhali ziinkqubo apho iiathom kunye neemolekyuli zidibana ukuze zenze izinto ezintsha. Ezi nkqubo zingenzeka ngeendlela ezahlukeneyo, kuxhomekeke ekubeni ubushushu buveliswa okanye bufunxwa ngexesha lokusabela. Kweli nqaku siza kuthetha ngomahluko phakathi kwe-endothermic reactions kunye ne-exothermic reactions.

ukusabela kwe-endothermic

Iintshukumo ze-Endothermic zezo apho ubushushu bufunxwa kokusingqongileyo ukuze buqhubele phambili impendulo. Oku kuthetha ukuba amandla eemveliso makhulu kunamandla e-reactants. Ke ngoko, iimpendulo ze-endothermic zifuna igalelo lamandla ukuze livuswe.

Imizekelo yokusabela kwe-endothermic

• Ukunyibilikisa ityuwa emanzini
• umkhenkce onyibilikayo
• Ifotosinthesisi

Kuzo zonke ezi meko, ukufunxwa kobushushu obuvela kwimo engqongileyo kuyimfuneko ukuze kwenzeke ukusabela kweekhemikhali.

ukusabela exothermic

Iimpendulo ze-exothermic zezo apho ubushushu bukhutshwa kwindawo eyingqongileyo ngexesha lokusabela. Kule meko, amandla e-reactants makhulu kunamandla eemveliso, ngoko ke ubushushu bukhutshwa. Iintshukumo zobushushu azidingi mthombo wamandla wangaphandle ukuze ziqhube.

Imizekelo yokusabela okugqithisileyo

• Ukutsha kwepetroli
• I-oxidation yeentsimbi
• Ukuvumba

Kule meko, ukukhululwa kobushushu yimveliso ye-chemical reaction.

Isiphelo

Isishwankathelo, ukuphendulwa kweekhemikhali kunokuba yi-endothermic okanye i-exothermic kuxhomekeke ekubeni ubushushu bufunnyiwe okanye bukhutshwe ngexesha lokuphendula. Iimpendulo ze-endothermic ziphawulwa ngokufuna umthombo wamandla wangaphandle, ngelixa iimpendulo ze-exothermic zivelisa ukukhutshwa kwamandla. Kubalulekile ukuqonda umahluko phakathi kwezi zintlu zimbini zokuphendulwa kweekhemikhali ukuze uqonde ngcono iinkqubo ezininzi kwikhemistri nakubomi bemihla ngemihla ngokubanzi.
