Eₐ = 60 kJ/mol = 60000 J mol⁻¹

R = 8.314 J mol⁻¹ K⁻¹

T = (273.2 + 23.0) K = 296.2 K

A = 7.80 × 10¹² M⁻¹ s⁻¹

According to Arrhenius Equation:

K = Ae^(-Ea/RT);

K = (7.80*10^12 M−1s−1)e^((-60000 J/mol)/(8.314 J/K·mol)(296.15 K))

K = (7.8*10^12)e^((-60000 )/((8.314)*(296.15))

K = 6.80 x 10^(12)
