Experiments were cоnducted tо study the rаte оf the reаction represented by the following equаtion: 2NO(g) + 2H2(g) ⟶ N2(g) + 2H2O(g) Initial concentrations and rates of reaction are given here Experiment Initial Concentration[NO] (mol L−1) Initial Concentration, [H2](mol L−1 min−1) Initial Rate of Formation ofN2 (mol L−1 min−1) 1 0.0060 0.0010 1.8 × 10−4 2 0.0060 0.0020 3.6 × 10−4 3 0.0010 0.0060 0.30 × 10−4 4 0.0020 0.0060 1.2 × 10−4 Consider the following questions:(a) Determine the order for each of the reactants, NO and H2, from the data given and show your reasoning.(b) Write the overall rate law for the reaction.(c) Calculate the value of the rate constant, k, for the reaction. Include units.(d) The following sequence of elementary steps is a proposed mechanism for the reaction.Step 1: NO + NO ⇌ N2O2Step 2: N2O2 + H2 ⇌ H2O + N2OStep 3: N2O + H2 ⇌ N2 + H2 OBased on the data presented, which of these is the rate determining step? What chemical species are intermediates? Show that the mechanism is consistent with the observed rate law for the reaction and the overall stoichiometry of the reaction.
