To determine the order of the reaction with respect to H₂, we need to compare the rate of the reaction in two experiments where the initial concentration of H₂ is different and the concentration of ICl remains constant. From experiment 1 and experiment 2, we can see that when the concentration of H₂ is the same, but the concentration of ICl has been reduced to one-fourth, the rate of reaction is also reduced to approximately one-tenth of its original value (0.331/34 = 0.0097, which is close to 0.01). This indicates that the reaction rate is directly proportional to the concentration of H₂ raised to the first power (i.e., the order of the reaction with respect to H₂ is 1). Therefore, the best choice is C: first order.
