Yog ∆S yog qhov zoo, qhov no txhais tau hais tias kev tsis sib haum xeeb ntawm lub ntiaj teb yog nce los ntawm reactants mus rau cov khoom. Qhov no kuj yog qhov zoo thiab nws feem ntau txhais tau tias ua ntau cov molecules. Cia peb saib qhov no los ntawm qhov kev pom zoo. Xav txog cov tshuaj tiv thaiv uas nyiam cov khoom ntawm qhov sib npaug.
Koj qhia li cas yog Delta S yog qhov zoo lossis tsis zoo rau qhov kev tawm tsam?
Thaum kwv yees seb puas muaj cov tshuaj tiv thaiv lub cev lossis tshuaj lom neeg yuav muaj qhov nce lossis txo qis hauv entropy, saib cov theem ntawm hom tam sim no. Nco ntsoov 'Tshis Me Me' los pab koj qhia. Peb hais tias ' yog tias entropy tau nce, Delta S yog qhov zoo' thiab 'yog tias qhov entropy tau qis, Delta S yog qhov tsis zoo.
txhais li cas thaum Delta S tsis zoo?
Ib tug tsis zoo delta S sib raug rau a spontaneous txheej txheem thaum qhov loj ntawm Tdelta S yog tsawg dua delta H (uas yuav tsum yog qhov tsis zoo). delta G=delta H - (Tdelta S). Qhov tsis zoo delta S yuav txhais tau tias cov khoom lag luam muaj qhov qis qis dua li cov reactants, uas tsis yog nws tus kheej.
Puas entropy nce thaum Delta S zoo?
Qhov twg delta ng yog qhov hloov pauv ntawm cov roj moles (qhov kawg - pib). Entropy, S, yog ib lub xeev muaj nuj nqi thiab yog ib qho kev ntsuas ntawm kev tsis sib haum xeeb los yog randomness. A qhov zoo (+) hloov pauv hloov pauvtxhais tau tias muaj kev cuam tshuam ntau ntxiv. Lub qab ntuj khwb nyhav mus rau qhov nce entropy.
Can Delta H thiab Delta S uazoo?
Gibbs lub zog tsis muaj zog cuam tshuam txog enthalpy, entropy thiab kub. Ib qho tshuaj tiv thaiv ib txwm tshwm sim thaum Delta H tsis zoo thiab Delta S yog qhov zoo, thiab cov tshuaj tiv thaiv ib txwm tsis yog tshwm sim thaum Delta H yog qhov zoo thiab Delta S tsis zoo.
