Show by uisng rate laws how much the rate of reaction `2NO(g) + O_(2)(g) rarr 2NO(g)` will change if the volume of the reaction vessel is diminished to `1//3` of its initial volume.

Answer

27 times

Explanation

Initially, rate `=k["NO"]^(2)["O"_(2)]=k" a"^(2)b("say").`
When volume is reduced to one-third, the concentration of each reactant will become three times.
New rate `=k(3" a")^(2)(3" b")=27" k a"^(2)b.`
