For the reaction 2NO(g)+2H2(g)→N2(g)+2H2O(g)2\text{NO}(\text{g})+2\text{H}_2(\text{g})\rightarrow\text{N}_2(\text{g})+2\text{H}_2\text{O}(\text{g}), the rate expressions are d[N2]dt=k1[NO][H2],d[H2O]dt=k[NO][H2],−d[NO]dt=k1′[NO][H2],−d[H2]dt=k1′′[NO][H2].\begin{aligned} \frac{d[\text{N}_2]}{dt}&=k_1[\text{NO}][\text{H}_2],\\ \frac{d[\text{H}_2\text{O}]}{dt}&=k[\text{NO}][\text{H}_2],\\ -\frac{d[\text{NO}]}{dt}&=k'_1[\text{NO}][\text{H}_2],\\ -\frac{d[\text{H}_2]}{dt}&=k''_1[\text{NO}][\text{H}_2]. \end{aligned} The relationship between kk, k1k_1, k1′k'_1, and k1′′k''_1 is: (a) k=k1=k1′=k1′′k=k_1=k'_1=k''_1 (b) k=2k1=k1′=k1′′k=2k_1=k'_1=k''_1 (c) k=2k1′=k1=k1′′k=2k'_1=k_1=k''_1 (d) k=k1=k1′=2k1′′k=k_1=k'_1=2k''_1
