In the reaction between NO and $\mathrm{H}_{2}$ the following data are obtained Experiment I: $\mathrm{P}_{\mathrm{H}_{2}}$ constant

$\mathrm{P}_{\mathrm{NO}}$ (mm of Hg)	359	300	152
$\frac{-\mathrm{dP}_{\mathrm{NO}}}{\mathrm{dt}}$	1.59	1.03	0.25

Experiment II : $\mathrm{P}_{\mathrm{NO}}=$ constant

$\mathrm{P}_{\mathrm{H}_{2}}$ (mm of Hg)	289	205	147
$\frac{-\mathrm{dP}_{\mathrm{H}_{2}}}{\mathrm{dt}}$	1.60	1.10	0.79

The orders with respect to $\mathrm{H}_{2}$ and NO are

(a)1 with respect to NO and 2 with respect to $\mathrm{H}_{2}$

(b)2 with respect to NO and 1 with respect to $\mathrm{H}_{2}$

(c)1 with respect to NO and 3 with respect to $\mathrm{H}_{2}$

(d)2 with respect to NO and 2 with respect to $\mathrm{H}_{2}$
