He rate constant for the forward reaction, k1, is 297 l·mol–1·min–1 and the rate constant for the reverse reaction, k–1, is 393 l·mol–1·min–1 at a given temperature. the activation energy for the forward reaction is 42.1 kj·mol–1, while the activation energy for the reverse reaction is 22.1 kj·mol–1. determine the equilibrium constant, k, of this reaction.
