Question

Which of the following factors are responsible for the increase in the rate of a surface catalyzed reaction?
1)A catalyst provides proper orientation for the reactant molecules to react
2)Heat of adsorption of reactants on a catalyst helps reactant molecules to overcome activation energy
3)The catalyst increases the activation energy of the reaction
4)Adsorption increases the local concentration of reactant molecules on the surface of the catalyst.
Select the correct answer using the code given below :

• A. 1 and 2
• B. 1 and 3
• C. 2, 3 and 4
• D. 1, 2 and 4

Answer 1

The correct option is D 1, 2 and 4

Rate of surface catalyzes reaction where the surface access increases of the ways which favours to increase surface are a of access will increase rate of this reaction.
Hence such points are 1, 2, & 4
So, ans is (4) (1, 2,& 4)
