The rate of a gaseous reaction is given ...

The rate of a gaseous reaction is given by the expression k [A] [B]. If the volume of the reaction vessel is suddenly reduced to `1//4th` of the initial volume, the reaction rate relating to original rate will be

A

`1/16`

B

`1/8`

C

8

D

16

Text Solution

Verified by Experts

The correct Answer is:
D
`r = K[A][B]`
`r_(1) = K[A]/(1/4) [B]/(1/4) = 16K[A][B]`

  • The mathematical expression which describes the reaction rate in terms of molar concentrations of the reactants as determined experimentally is called rate law. The sum of the coefficients of the reacting species that are involved in the rate equation of a particular reaction is known as the order of the reaction, The reactions may be classified as first, second and third order reactions depending upon the number of of reacting species involved in the rate equation. It can be fractional in complex reations and even zero in certain reactions such as photochemicla reactions. The units of the rate constant(k) can help ini predicting the nature of a particular reaction. The rate of a gaseous reaction is given by the expression : k[A][B] . If the volume of the reaction mixture is suddenly reduced to 1//4th of its initial volume, the reaction rate relating to original rate will be:
