Solution

The correct option is A Order of reaction is always whole number
If rate is given by: rate $= k [A]^{x} [B]^{y}$
then the order =x+y.
This order can be a positive, negative no., zero or even fractional. It can be determined only experimentally and does not depend on stoichiometric coefficients of reactants.

Q. Assertion :For the reaction

H_{2} + I_{2} ⇌ 2 H I, K_{p} = K_{c}

. Reason: If

K_{p} = K_{C}

for a reaction, the sum of stoichiometric coefficient of reactants should be equal to the sum of stoichiometric coefficients of products.
