Which is not the correct statement for a catalyst?
(A) It does not alter activation energy for backward reaction
B) The surface of heterogenous catalyst adsorbs reactants
c) Catalyst may form intermediates with reactants
D) Action of enzyme catalyst is specific

Which of the following is correct plot for effect of catalyst on activation energy.

Which of the following statements is/are correct in the case of heterogenous catalyst?

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 .

What is the effect of adding a catalyst on (a) Activation energy (Ea), and (b) Gibbs energy ( DeltaG ) of a reaction?

For a reaction A_(2)+B_(2) hArr 2AB the figure shows the path of the reaction in absence and presence of a catalyst what will be the energy of activation for forward (E_(f)) and backward (E_(b)) reaction in presence of a catalyst and Delta H for the reaction gt the dotted curve is the path of reaction in presence of a catalyst .
