The reaction,`2NO(g)+O_(2)(g)hArr2NO_(2)(g),` is of first order. If the volume of reaction vessel is reduced to `(1)/(3)`, the rate of reaction would be

Options

A. `1//3` times
B. `2//3` times
C. 3 times
D. 6 times

Answer

C

Explanation

For following reaction `2NO_((g))+O_(2)(g)to2NO_(2)(g)` When the volume of vessel change into `(1)/(3)` then concentration of reactant become three times . The rate of reaction for first order reaction `prop` concentration . So rate of reaction will increases three times .
