Activation energy of a chemical reaction can be determined by

Options

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

c

Explanation

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