Assertion : A catalyst lowers the threshold energy level for a reaction Reason : A catalyst combines with one of the reactans of from an intermediate the follows an alternate path with lesser energy of activation.
Statements : A catalyst doesnot alter the equilibrium constant os a reaction . Expabnations : A catalyst complex with the reactants and provides an alternate path wirh a lower energy of activation for the reacton . The forwaord and forwad and reverse reactions are affected to the same extent .
Statement: A catalyst always lower the energy of ectivation. Explanation: The catalyst-reactant interaction forms activated adsorbed complex and adsorption is always exothermic.
Statements : In catalysis , the eneire reaction occurs in a single phase Explanations : Catalystic ation of a surface depends on its abosrupoint of the reactants .
Statements : A catalyst enhances the rate of a reactgion . Expabnations : The energy foactivation of the reaction is lowered in presence of a catarge of the coagualnt ion.
Statements : The activity of catalyst is more or less specific. Explanations : A catalyst for one reaction is not necessary to catlyse the other reaction .
