You have a process where A= B and initially the forward rate constant is equal to 10.3 s-1 and the reverse rate constant is equal to 17.8 5-1. Suddenly, the temperature is changed from 285.5 K to 325.1 K. If the activation energy of the forward process is 47.0 kJ mol-1, and the activation energy of the reverse process is 53.7 kJ mol-1, determine the equilibrium constant, K, at 325.1 K. Express your answer to the second decimal place (XX.XX)....
