Question

Activation energy of a chemical reaction can be determined by:

(a) determining the rate constant at standard temperature.
(b) determining the rate constants at two temperatures.
(c) determining the probability of collision.
(d) using catalyst.

Answer 1

(b) determining the rate constants at two temperatures.

Knowing k₁ and k₂ at T₁ and T₂, E_a can be determined. (Arrhenius equation)
