Question
If $\Delta\text{G}^\circ$ for reversible reaction is found to be zero, what is the value of its equilibrium constant?
✓

Answer

$\Delta\text{G}^\circ=0\ (\text{given})$$\Delta\text{G}^\circ=-2.303\text{ RT log K}=0$
$\Rightarrow\log\text{K}=0$
$\Rightarrow\log\text{K}=\log1$
$\Rightarrow\text{K}=1.$ $[\because\log1=0]$
