Molar composition of a mixture of P and Q at equilibrium is $3: 1(\mathrm{P}: \mathrm{Q})$. A small disturbance in composition results in change of chemical potential of P by $10 \mathrm{J} \mathrm{mol}^{-1}$. The chemical potential of Q will change (in $\mathrm{J} \mathrm{mol}^{-1}$) by (1) 30 (2) 3.3 (3) -30 (4) -3.3 Options
