Question
Chemistry Question on Surface Chemistry
Which one of the following statements is incorrect in the case of heterogeneous catalysis ?
A
The catalyst lowers the energy of activation
B
The catalyst actually forms a compound with the reactant
C
The surface of the catalyst plays a very important role
D
There is no change in the energy of activation.
Answer
There is no change in the energy of activation.
Explanation
Solution
The theory of heterogeneous catalysis is based upon the phenomenon of adsorption. The activity of catalyst is due to the presence of free valencies on its sufrace due to which surface of catalyst has force of attraction
