Question

Note: In the following questions two or more options may be correct.
Which of the following statements are correct about solid catalyst? [NCERT Exemplar]
(a) Same reactants may give different product by using different catalysts.
(b) Catalyst does not change AH of reaction.
(c) Catalyst is required in large quantities to catalyse reactions.
(d) Catalytic activity of a solid catalyst does not depend upon the strength of chemisorption.

Answer 1

Answer:

a and b are correct

Explanation:

In some reactions, same reactants may give different products by using different catalysts. A catalyst doesn't change heat of reaction because the activation energy of both forward and backward reactions are affected equally by the catalyst.
