Problem
Consider the reversible reaction A(g) + B(g) ⇌ AB(g). The activation energy of the backward reaction exceeds that of the forward reaction by 2RT (in J mol−1). If the pre-exponential factor of the forward reaction is 4 times that of the reverse reaction, the absolute value of ΔG° (in J mol−1) for the reaction at 300 K is ____. (Given: ln(2) = 0.7, RT = 2500 J mol−1 at 300 K.)
