Question

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 1/4 th
of the initial volume, the reaction rate relating to original rate
will be:
a 1/10
b 1/8
c 8
d 16

Niyati · Accepted Answer

AS rate =K[A][B] where [A] = conc of A
[B] = conc of B

conc = no of moles / volume

therefore we decrease the volume of vessel to1/4 th intial volume
the conc of A and B both will increase by 4 times { conc is
inversely propotional to volume }
so final conc of A will become = 4[A]
final conc of B will become = 4[B]

final rate of rxn = k{4[A]*4[B] }
= 16k[A][B]
= 16 {intial rate of rxn}

so te correct option is D

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 1/4 th of the initial volume, the reaction rate relating to original rate will be: a. 1/10 b. 1/8 c. 8 d. 16
