42. Solution to Chemistry Problem

3. For reaction (A), occurring in the n-th order, the rate constants at different temperatures are known. [For reaction n — 1, k has the dimension of s-1, and for n — 2, the dimension of k is cm3/(s*mol).] Calculate: a) activation energy; b) pre-exponential factor; c) heat of activation; d) entropy of activation; e) temperature coefficient of reaction rate.
