In an environmental chemistry experiment, researchers tracked the decomposition of an organophosphate pesticide P in water. The reaction was studied at two temperatures with identical initial [P] and pH. Initial rates were measured over the first minute. Conditions: - At 20°C: v0v_0 = 2.0 × 10−8^{-8} M/s - At 30°C: v0v_0 = 6.0 × 10−8^{-8} M/s Assuming the rate law form and concentrations are unchanged between trials, which factor most directly explains the higher initial rate at 30°C?
