Consider a batch reactor with an initial concentration of A $($CA$0)$ of $2\mathrm{.}0$ mol$/$L$.$ The rate constant $($k$)$ for the reaction is $0\mathrm{.}1$ s$1.$ You are required to model the concentration profile of A over a period of $10$ seconds using the fourth$-$order Runge$-$Kutta method. formulate the first$-$order ordinary differential equation $($ODE$)$ governing the concentration of

A with respect to time
