Question

Consider the reaction $A \rightleftharpoons B$ at $1000\, K$ At time '$t$', the temperature of the system was increased to $2000 \,K$ and the system was allowed to reach equilibrium. Throughout this experiment the partial pressure of $A$ was maintained at $1$ bar. Given below is the plot of the partial pressure of $B$ with time. What is the ratio of the standard Gibbs energy of the reaction at $1000\, K$ to that at $2000\, K$ ?
