According to the collision model of kinetics, certain activation energy must be overcome before a reaction can proceed. Based on the data given below, what is a reasonable estimate of the activation energy for the decomposition of NOCl ?
2 NOCl(g) → 2 NO(g) + Cl2(g)
Temperature (K) Rate constant, k (L/mol s)
400 6.6 × 10–4
500 2.9 × 10–1
600 1.63 × 101
