Prof. Anil Thomas and Prof. Santosh Yadav Solutions for Chapter: Chemical Kinetics, Exercise 2: Critical Thinking

What happens when the temperature of a solution is increased from $25°\mathrm{C} \mathrm{to} 52°\mathrm{C}$?

The rate constant is given by the equation $\mathrm{k}={\mathrm{pze}}^{\frac{-{\mathrm{E}}_{\mathrm{a}}}{\mathrm{RT}}}$. Which factor should register a decrease for the reaction to proceed more rapidly?

The rate constants at $27°\mathrm{C} \text{and }67°\mathrm{C}$ for the dissociation of ${\mathrm{N}}_{\mathrm{2}}{\mathrm{O}}_{\mathrm{5}} \text{are}{ 3.45 \times 10}^{\mathrm{-5}} \text{and}{ 6.90 \times 10}^{\mathrm{-3}}$ respectively. What is the activation energy for the dissociation of ${\mathrm{N}}_{\mathrm{2}}{\mathrm{O}}_{\mathrm{5}}$?
