Question

For the reaction: $\mathrm{H}_{2(g)}+\mathrm{I}_{2(g)} \rightleftharpoons 2 \mathrm{HI}_{(g)}$, the standard free energy is $\Delta G^{\circ}>0$.
The equilibrium constant ( $K$ ) would be $\_\_\_\_$ .

Professor PC Thomas Classes · Answer

(d): $\Delta G^{\circ}=-R T \ln K$ If $\ln K=-\mathrm{ve}$ then only $\Delta G^{\circ}=+\mathrm{ve}$ (or $>0$ ). Thus, $K<1$
