Question

What will be the shape of the curve if the concentration of the reactant is plotted against time for a first order reaction?

Answer 1

We know that

[A] = [A]₀ e^−kt

According to this equation, a first-order process is exponential, and the reactant concentration drops exponentially over time. Therefore, an exponential decay curve is produced when a graph is plotted between the reactant concentrations at various points in time.
