Detailed Explanation
In chemistry, many reactions can be modeled using differential equations that describe how concentrations of reactants change over time. Numerical solvers help chemists predict how reactions will progress, allowing for better control of processes in laboratories or industrial settings.
Examples & Analogies
Imagine you are baking a cake. The way the ingredients react when mixed and heated can be compared to a chemical reaction. If you add too much of one ingredient (like baking powder), the cake could overflow or not rise properly.
