What is the expression of zero order reaction?

The expression for a zero-order reaction indicates that the rate of reaction is constant and independent of the concentration of the reactants. It can be mathematically represented as ( \text{Rate} = k ), where ( k ) is the rate constant. The concentration of the reactant decreases linearly over time, and the integrated rate law is given by ( [A] = [A_0] - kt ), where ([A_0]) is the initial concentration and ( t ) is time.
