Answer to Problem 4.29P
The standard free energy of activation for reaction B is
Explanation of Solution
It is given that standard free energy of activation of reaction A is
The relative rates of two reactions are expressed as,
Where,
•
•
•
Substitute the activation energy for reaction A, the relative rate of A and B, gas constant and temperature in the given formula.
Rearrange the above equation for the calculation of activation energy of B as shown below.
Thus, standard free energy of activation for reaction B is
The standard free energy of activation for reaction B is
