A) It initiates the reaction
B) It changes the state of equilibrium in favour of formation of product
C) It provides an alternative reaction path of lower activation energy
D) It provides activation energy to the reactants
Correct Answer: C
Solution :
A catalyst which increases the rate of reaction is called positive catalyst. The general characteristics of positive catalyst are as : (I) The catalyst does not alter (change) the position of equilibrium. (II) Catalyst does not initiate a reaction. (Ill) The catalyst decreases the activation energy of the reaction and hence, increase the rate of reaction. (IV) It does not provide activation energy to the reactant. Therefore, statement is correct, ie, it provides an alternative reaction path of lower activation energy.
