For the reaction system : 2NO(g)+O2(g)→2NO2(g) volume is suddenly reduced to half its value by increasing the pressure on it.If the reaction is of first order with respect to O2 and second order with respect to NO, the rate of reaction will be _____?

The rate law of the reaction is Rate $= k [O_{2}] {[N O]}^{2} .$

when volume is reduced to half, the concentration becomes double from the initial concentration, so the rate law becomes

Rate $= k [2 O_{2}] {[2 N O]}^{2} = 8 k [O_{2}] {[N O]}^{2}$

For the reaction system : $2 N O (g) + O_{2} (g) \to 2 N O_{2} (g)$
volume is suddenly reduced to half its value by increasing the pressure on it.
If the reaction is of first order with respect to $O_{2}$ and second order with respect to NO, the rate of reaction will be _____?
