The rate law for

$2NO(g)+2H_2(g)N_2(g)+2H_{2}O(g)$

is rate $=k[NO{]}^2[H_2].$

The following mechanisms have been proposed:

A$.$

$A.2NO(g)+H_2(g)N_{2}O(g)+H_{2}O(g)[slow]$

$N_{2}O(g)+H_2(g)N_2(g)+H_{2}O(g)[fast]$

$[$fast$]$

B$.$

$NO(g)+H_2(g)N(g)+H_{2}O(g)$

$N(g)+NO(g)N_2(g)+O(g)$

$O(g)+H_2(g)H_{2}O(g)$

$[$fast$]$

$[$slow$]$

$[$fast$]$

c$.2NO(g)N_2{O}_2(g)$

$[$fast$]$

$N_2{O}_2(g)+H_2(g)N_{2}O(g)+H_{2}O(g)$

$N_{2}O(g)+H_2(g)N_2(g)+H_{2}O(g)$

$[$slow$]$

$[$fast$]$

Part: $\frac{0}{2}$

Part $1$ of $2$
