| 1. The minimum amount of energy that must be possessed by colliding molecules for a reaction to occur is referred to as activation energy. |
|
|
| 2. An exothermic reaction does not require activation energy. |
|
|
| 3. The smaller the activation energy the slower is the rate of reaction. |
|
|
| 4. Activation energy of an endothermic reaction is higher than that of an exothermic reaction |
|
|
| 5. Rate of reaction is the rate of change of an amount or concentration of a particular reactant or product per unit time. |
