Question

For the reaction, $2 N O (g) + 2 H_{2} (g) \to N_{2} (g) + 2 H_{2} O (g)$ the rate expression can be written in the following ways:
${d t [N_{2}] / d t} = k_{1} [N O] [H_{2}]; {d [H_{2} O] / d t) = k [N O] [H_{2}];$
${- d [N O] / d t} = k_{1}^{'} [N O] [H_{2}]; {- d [H_{2}] / d t} = k_{1}^{''} [N O] [H_{2}]$
The relation ship between $k, k_{1}, k_{1}^{'}$ and $k_{1}^{''}$ is:

Solution

$2 N O_{(g)} + 2 H_{2} (g) \to N_{2} (g) + 2 H_{2} O (g)$
$- \frac{1}{2} \frac{d [N O]}{d t} = \frac{- 1}{2} \frac{d [H_{2}]}{d t} = \frac{d [N_{2}]}{d t} = \frac{1}{2} \frac{d [H_{2} O]}{d t}$
$- \frac{d [N O]}{d t} = \frac{- d [H_{2}]}{d t} = \frac{2 d [N_{2}]}{d t} = \frac{d [H_{2} O]}{d t}$
$\begin{matrix} \frac{d [N_{2}]}{d t} = k_{1} [N O] [H_{2}] \frac{d [H_{2} O]}{d t} = k [N O] [H_{2}] - \frac{d [N O]}{d t} = k_{1}^{'} [N O] [H_{2}] - \frac{d [H_{2}]}{d t} = k "_{1} [N O] [H_{2}] \end{matrix} ⎫ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎬ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎪ ⎭ G i v e n$
put given data in equation (i)
$k_{1}^{'} [N O] [H_{2}] = k "_{1} [N O] [H_{2}] = 2 k_{1} [N O] [H_{2}] = k [N O] [H_{2}]$
$k_{1}^{'} = k "_{1} = 2 k_{1} = k$
