Question

The rate of a gaseous reaction is given by the expression k [ A ][ B ]2 . If the volume of vessel is reduced to one half of the initial volume, the reaction rate as compared to original rate is (A) (1/16) (B) (1/8) (C) 8 (D) 16

Tardigrade Admin · Accepted Answer

r = K [ A ][ B ]2 When volume is reduced to half, pressure increases by two times. r = k [2 A ]1[2 B ]2=2 × 4=8 times

Q. The rate of a gaseous reaction is given by the expression $k [A] [B]^{2} .$ If the volume of vessel is reduced to one half of the initial volume, the reaction rate as compared to original rate is

$\frac{1}{16}$

$\frac{1}{8}$

$r = K [A] [B]^{2}$
When volume is reduced to half, pressure increases by two times.
$r = k [2 A]^{1} [2 B]^{2} = 2 \times 4 = 8$ times
