WebbThe integrated rate law equation varies depending on the order of the reaction. These equations can take the linear form y=mx+b. Thus, a plot of concentration versus time yields a linear plot for a zero-order equation, a plot of the natural log of concentration versus time yields a linear plot for a first-order equation, and so on. WebbZero-order reaction is a chemical reaction wherein the rate does not vary with the increase or decrease in the concentration of the reactants. Therefore, the rate of these reactions is always equal to the rate …
