Text solutionVerified

(A) Positive catalyst increases the rate of reaction. It increases the rate of forward as well as reverse reaction. Hence, equilibrium is quickly attained.

(B) During the course of the reaction, specific reaction rate remains constant. It is independent of the reactant concentration and varies only with temperature.

(C) Rate constant always increases with rise in temperature whether the reaction is endothermic or exothermic. This is in accordance with Arrhenius equation which gives the temperature dependence of reaction rates.

Hence, all the statements are correct.
