Use the collision theory of gas phase reactions to calculate the theoretical value of the second order rate constant for the reaction H22(g) + I22(g) →→ 2 HI(g) at 650 K, assuming that it is elementary bimolecular. Assume the collision cross section is 0.40 nm22, the reduced mass is 3.32 times 10−27−27 kg, and the experimental activation energy is 171 kJ mol−1−1.
