For the reaction system 2 NO(g) + O2(g) → 2 NO2(g) the volume is suddenly reduced to half its value by increasing the pressure on it. lf the reaction is first order with respect to O2, and second order with respect to NO, the rate of reaction will
1
increase to four times of its initial value
2
decrease to one-fourth of its initial value
3
decrease to one-sight of its initial value
4
increase to eight times of its initial value
