Final answer:
The rate constant (k) for the reaction 2NO(g) + Cl2(g) → 2NOCl(g) is 9.1 L2 mol-2 h-1, as directly provided in the information given with the question.
The right answer is b. 2.28 mol L^(-1) h^(-1)
Step-by-step explanation:
The student asked for the rate constant (k) for the reaction 2NO(g) + Cl2(g) → 2NOCl(g). Based on the given information, which shows that the reaction is second order in NO and first order in Cl2, with a rate law expressed as rate = k[NO]2[Cl2], and with a provided rate constant of k = 9.1 L2 mol-2 h-1, we can answer the student's question directly.
We do not need to calculate using the rate constant options given in the question (a. 1.14, b. 2.28, c. 3.42, d. 4.56), because the correct value of k is already provided in the question's background information. Therefore, the rate constant for the reaction is k = 9.1 L2 mol-2 h-1.
The right answer is b. 2.28 mol L^(-1) h^(-1)
