Zero Order Reactions: A zero order reaction is a type of chemical reaction where the rate of reaction is independent of the concentration of the reactants. This means that the rate of the reaction remains constant over time, regardless of how much reactant is present.

Zero Order Reactions

Mathematically, a zero-order reaction can be expressed as:

Rate = k

where “k” is the rate constant of the reaction. The units of k depend on the overall reaction order.

In practical terms, a zero-order reaction can be recognized by a linear relationship between the concentration of the reactant and time. This means that the concentration of the reactant decreases at a constant rate over time, as the reaction proceeds.

Examples of zero-order reactions include the decomposition of a stable compound such as hydrogen peroxide or the oxidation of alcohol by liver enzymes. In these reactions, the rate of the reaction is not affected by the concentration of the reactants, but rather by other factors such as temperature, catalysts, or other reaction conditions.
