What is known as activation energy? How is activation energy affected by (i) the use of a catalyst ? (ii) a rise in temperature ? |
|
Answer» Solution :Activation energy is the extra energy that must be SUPPLIED to the reactants so that they can change into products. (i) Activation energy is LOWERED by the use of a catalyst. This is because the catalyst reacts with the reactants to from an intermediate complex which changes into the product. The FORMATION of intermediate complex involves lower activation energy as it is formed EASILY. (ii) There is no EFFECT of activation energy with the increase of temperature. |
