48. Solution to Chemistry Problem

9. For a reaction proceeding in the n -th order, the values ​​of the rate constants at different temperatures are obtained. For reactions with n = 1, the constant has the dimension of s-1, and for n = 2, the dimension is cm3/s.mol. Calculate:
1. Activation energy;
2. Pre-exponential factor;
3. Heat of activation;
4. Temperature coefficient of reaction rate;
5. The amount of substance consumed during time τ, if the initial concentrations are equal to C0 (kmol/m3)
