In the reaction between NO and $\mathrm{H_2}$ the following data are obtained Experiment I: $P_{\mathrm{H_2}}$ constant

$P_{\mathrm{NO}}$ (mm of Hg)	359	300	152
$-\dfrac{dP_{\mathrm{NO}}}{dt}$	1.50	1.03	0.25

Experiment II : $P_{\mathrm{NO}}$ = constant

$P_{\mathrm{H_2}}$ (mm of Hg)	289	205	147
$-\dfrac{dP_{\mathrm{H_2}}}{dt}$	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 $\mathrm{H}_{2}$
