In an experiment on hydrogen adsorption on two different faces of a copper crystal, the activation energy on Face 1 (Ea1) was 28 kJ/mol and on Face 2 (Ea2) was 33 kJ/mol. Assuming Arrhenius behavior and identical frequency factors, the ratio of the rate of adsorption on Face 1 to that on Face 2 at 250 K is approximately: (Given: R = 8.314 J/(mol·K), e2.4 ≈ 11.0)
