For the reaction of H2H_2 with I2I_2, the rate constant is 2.5×10−4 dm3 mol−1 s−12.5 \times 10^{-4} \text{ dm}^3 \text{ mol}^{-1} \text{ s}^{-1} at 327∘C327^\circ \text{C} and 1.0 dm3 mol−1 s−11.0 \text{ dm}^3 \text{ mol}^{-1} \text{ s}^{-1} at 527∘C527^\circ \text{C}. The activation energy for the reaction, in kJ mol−1\text{kJ mol}^{-1} is: ( R=8.314 J K−1 mol−1R=8.314 \text{ J K}^{-1} \text{ mol}^{-1} ) (1) 72 (2) 166 (3) 150 (4) 59
