"WebFor a second-order reaction, $ t_{\frac{1}{2}} $ is inversely proportional to the concentration of the reactant, and the half-life increases as the reaction proceeds because the concentration of reactant decreases. Consequently, we find the use of the half-life concept to be more complex for second-order reactions than for first-order reactions " - How to solve for k in a second order reaction
