The rate of a gaseous reaction is given by the expression K[A]2[B]3. The volume of the reaction vessel is reduced to one half of the initial volume. What will be the reaction rate as compared to the original rate a?

Question

The rate of a gaseous reaction is given by the expression K[A]2[B]3. The volume of the reaction vessel is reduced to one half of the initial volume. What will be the reaction rate as compared to the original rate a? (A) (1/8) a (B) (1/2) a (C) 2a (D) 32a

Rate = k[A]2 [B]3 = a When volume is reduced to one half then conc, of reactants will be doubled. Rate = k[2A]2 [2B]3 = 32 K[A]2 [B]3 = 32a

Q. The rate of a gaseous reaction is given by the expression $K [A]^{2} [B]^{3}$ . The volume of the reaction vessel is reduced to one half of the initial volume. What will be the reaction rate as compared to the original rate $a$ ?

$\frac{1}{8} a$

$\frac{1}{2} a$

$2 a$

$32 a$

Rate $= k [A]^{2} [B]^{3} = a$
When volume is reduced to one half then conc, of reactants will be doubled.
Rate = $k [2 A]^{2} [2 B]^{3} = 32 K [A]^{2} [B]^{3} = 32 a$
