General Principles and processes of Isolation of Elements
easy
નીચે પૈકી કઈ ખોટી અભિવ્યક્તિ છે:
A
$\frac{\Delta {G}_{\text {System }}}{\Delta {S}_{\text {Total }}}=-{T}($ અચળ ${P}$ પર $)$
B
$\ln {K}=\frac{\Delta {H}^{\circ}-{T} \Delta {S}^{\circ}}{{RT}}$
C
${K}={e}^{-\Delta {G}^{\circ} / {RT}}$
D
સમતાપી પ્રક્રિયા માટે ${w}_{\text {revesible }}=-{nRT} \ln \frac{{V}_{f}}{{~V}_{i}}$
(JEE MAIN-2021)
Solution
$\Delta {G}^{\circ}=-{RT} \ell {n} {K}$
$\Delta {H}^{\circ}-{T} \Delta {S}^{\circ}=-{RT} \ell {n} {K}$
$\ell {nK}=-\left[\frac{\Delta {H}^{\circ}-\Delta {S}^{\circ}}{{RT}}\right]$
