Activation energy of a chemical reaction can be determined by

Options

A. determining the rate constant at standard temperature
B. determining the rate constant at two temperatures
C. determining probability of collision
D. using catalyst.

Answer

B

Explanation

Knowing `k_1` and `k_2` at `T_1` and `T_2`, activation energy can be determined by using Arrhenius equation, i.e..
` log "" (K_2)/(k_1) = (E_a)/( 2.303 R) ((T_2 -T_1)/(T_1 T_2))`
