(a) Order of a reaction: The order of a reaction refers to the exponent to which the concentration of a reactant is raised in the rate equation. It defines how the rate of a chemical reaction depends on the concentration of reactants. The order can be determined experimentally and can be zero, first, second, or higher order.<\/h3>\n<h3>For example, in a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants. In a first-order reaction, the rate of the reaction is directly proportional to the concentration of one reactant. In a second-order reaction, the rate of the reaction is proportional to the square of the concentration of one reactant or to the product of the concentrations of two reactants.<\/h3>\n<h3>(b) Activation energy: Activation energy is the minimum amount of energy that must be overcome for a chemical reaction to occur. It represents the energy barrier that reactant molecules must overcome to transform into product molecules during a chemical reaction.<\/h3>\n<h3>In a reaction mechanism, the activation energy is the energy difference between the energy of the activated complex (transition state) and the energy of the reactants. Higher activation energy implies a slower reaction rate because it requires more energy for the reactant molecules to reach the transition state. Activation energy is a key parameter in determining the rate of a chemical reaction.<\/h3>\n","protected":false},"excerpt":{"rendered":"<p>Define the following terms : (a) Order of a reaction (b) Activation energy Ans.
