For the reaction system $2NO_{(g)} + O_{2(g)} \to 2NO_{2(g)}$,the volume is suddenly reduced to half its initial value by increasing the pressure. If the reaction is of first order with respect to $O_2$ and second order with respect to $NO$,the rate of reaction will:
- ADiminish to one fourth of its initial value
- BDiminish to one eighth of its initial value
- CIncrease to eight times of its initial value
- DIncrease to four times of its initial value
