Statements : The activity of catalyst is more or less specific.
Explanations : A catalyst for one reaction is not necessary to catlyse the other reaction .

The use of a catalyst in chemical reaction…activation energy of the reaction

Statements : A catalyst lowers the threshokd energy level for reaction . Explanations : Catalyst combines with reactabnt to form an exothermic intermediate and provide another parthway to traction .

Catalyst makes a reaction more exothermic.

Catalyst makes a reaction more exothermic.

Statement: A catalyst always lower the energy of ectivation. Explanation: The catalyst-reactant interaction forms activated adsorbed complex and adsorption is always exothermic.

Explain the effect of catalyst on the activation energy of the reaction with the graph.

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 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 .
