For the reaction system $2NO(g) + {O_2}(g) \to 2N{O_2}(g)$ volume is suddenly produced 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
Diminish to one fourth of its initial value
Diminish to one eighth of its initial value
Increase to eight times of its initial value
Increase to four times of its initial value

Decay of $_{92}{U^{235}}$is .....order reaction
Reaction $2A + B \to$ product, rate law is $\frac{{ - d[A]}}{{dt}}\, = \,K[A].$ At a time when $t\, = \,\frac{{{t_{1/2}}}}{{\ln\,2}},$ concentration of the reactant is
The specific rate constant of a first order reaction depends on the
