If the volume of the vessel in which the reaction 2NO_((g)) + O2_((g)) rarr 2NO_(2(g)) is occurring is diminished to 1//3^(rd) of its initial volume. The rate of the reaction will be increased by

Answer»

3 TIMES
9 times
27 times
36 times

Solution :For a given reaction
`2NO_((G)) + O_(2(g))hArr2NO_(2(g))`
Rate of reaction = `k[NO]^(2)[O_2]`
Rate of reaction directly proportional to concentration of the COMPOUND or inversely proportional to the VOLUME of the vessel.
i.e. `Cpropn/V`
If volume of vessel is reduced by 1/3rd of its initial value, then concentration of compound is increased by 3 times and consequently the rate of reaction by 27 times.
