A Catalyst provides energy to reactants for procedure and required energy for the reaction reduces.

A catalyst increases the rate of reaction by decreasing the activation energy of reacting molecules. If the activation energy is lower then the rate of reaction will automatically increase.

I think a catalyst gives an alternate reaction mechanism with lower activation energy.

It cannot lower the activation energy.

Why not A is the answer?

How activation energy is decreased?

Ronak Pahadia said:   7 years ago
Catalyst doesn't only lower the activation energy but it can also increase the activation energy in case of unfavorable reaction or to increase the reaction time?

I think catalyst reduce the require activation energy of reactant to made in activated state for reaction. Give fast reaction at low energy.

Actually I think D is also correct as the catalyst can be recovered after the reaction unchanged.

Differentiate between homogeneous and heterogeneous catalyst?

Deepak Bhengra said:   1 decade ago
A catalyst is defined as a substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process.
