Which of the following statements are correct about solid catalyst?
(i) Same reactants may give different product by using different catalysts.
(ii) Catalyst does not change of reaction.
(iii) Catalyst is required in large quantities to catalyse reactions.
(iv) The catalytic activity of a solid catalyst does not depend upon the strength of chemisorption.
Answers (1)
The answer is the option (i, ii)
Catalysts are highly selective in nature. They may act as a catalyst for a particular reaction but might not have any effect on the other. In addition, using different catalysts for same reaction may yield different products. Catalyst does not change the enthalpy of reactions. Enthalpy of a reaction is defined as the difference between the enthalpy of reactants and products. Therefore, catalyst has no role to play in the enthalpy of a reaction.
