Question

1. For the reaction,
2NO(g) + 2H2(g) → N2(g) + 2H2O(g)
The rate expression can be written in the following wa
d[N2]
d[
HO]
Ek [NO] [H2];
k [NO] [H]
dt
dt
d[NO]
d[H2]
= kz[NO] [H2);
k [NO] [H]
dt
dt
The relationship between k,, k2, kz, k, is
(a) k, = k, = kz = k4 (b) k2 = 2k, = kz = k4
(c) k= 2k2 = k, = ka (d) k2 = k, = kz = 2k4​
