A chemical reaction’s rate of change is observed over time. The rate of change of concentration of a particular reactant, $R$, with respect to time $t$ (in minutes) is given by the function $\frac{dR}{dt} = 5te^{-0.2t} - \cos(0.5t)$, where $R(t)$ is measured in mol/L.
b. If the initial concentration of the reactant is $R(0) = 10$ mol/L, determine the specific concentration function $R(t)$. Then, evaluate the concentration of the reactant after 5 minutes, correct to three decimal places.
