Question
Which of the following statements are correct?
Options
A.The efficiency of a heterogeneous catalyst depends upon its surface area.
B.Catalyst operates by providing alternate path for the reaction that involves a lower activation energy.
C.Catalyst lowers the energy of activation of the forward direction without affecting the energy of activation of the backward direction.
D.Catalyst does not affect the overall enthalpy change of the reaction.
Solution
Efficiency of a heterogeneous catalyst increases with its surface area.
Catalyst provides a path of lower activation energy but enthalpy of reaction is not affected.
Catalyst provides a path of lower activation energy but enthalpy of reaction is not affected.
