First order rate constant k is described in V=k[EA] while second order rate constant is given as V=k[E][A]. For reactions that do not have true order, k is the apparent rate constant.
A rate constant
The rate constant k in a chemical reaction can be determined by conducting experiments to measure the reaction rate at different concentrations of reactants. By plotting the data and using the rate equation, the rate constant k can be calculated.
The relative rate constant is a ratio of the rate constants of two reactions in a chemical reaction mechanism. It is used to determine the rate of reaction between different reactants in relation to each other.
The rate constant k is dependent on factors such as temperature, concentration of reactants, presence of catalysts, and the nature of the reaction mechanism.
The rate constant must have units that make the rate equation balanced. For example, if the rate law is rate kA2B, the rate constant k must have units of M-2 s-1. To calculate the rate constant, you can use experimental data and the rate law equation to solve for k.

how does the rate law show how concentration changes after the rate of reaction
The zero order reaction rate law states that the rate of a chemical reaction is independent of the concentration of the reactants. This means that the rate of the reaction remains constant over time. The rate of the reaction is determined solely by the rate constant, which is specific to each reaction. This rate law is expressed as: Rate k, where k is the rate constant.
