solve Question 1,2,3 and 4 in detail
1. What is the Gibbs free energy change at the transition state when AH at the transition state is 40 kJ/mol and AS at transition state is 80 J/mol at 350K? 2. What is the Activation Energy of a reverse reaction at 685K if the forward reaction has a rate constant of 52 M's', a pre-exponential factor of 30 M's', and a AH of reaction of 25 kJ/mol? 3. Given that the rate constant is 12 M's at 350 K and the pre- exponential factor is 22 M's", calculate the activation energy. 4. For a consecutive reaction (A>B→C) if k¡ is 5.65x10³ min' and the time necessary to reach the maximum conc. of B is 26 min. what is the value of k2?
