Question

Activation energy of a chemical reaction can be determined by
A. Changing concentration of reactants
B. Evaluating rate constant at standard temperature
C. Evaluating rate constants at two different temperatures
D. Evaluating velocities of reaction at two different temperatures

Answer 1

Correct Answer - c
log `(k_(2))/(k_(1)) = (E_(a))/(2.303R) [(T_(2) - T_(1))/(T_(1)T_(2))]`
