Question:

Which of the following statements about catalyst is true ?

Options:

A catalyst accelerates the reaction by bringing down the energy of activation.

A catalyst does not take part in the reaction

Both option (1) and (2) are correct.

None of the above

Correct Answer:

Both option (1) and (2) are correct.

Explanation:

A catalyst increases the rate of the reaction by lowering the activation energy.

The diagram suggests the activation energy with the catalyst and without the catalyst as below:

As Catalyst increases the reaction rate by lowering the activation energy, So,

Catalyst does not take part actively in the reaction, it just is consumed in one step and regenerated in another step. and it requires in a very small quantity.
