Substance A undergoes a first order reaction A  B with a half- life of 20 min at 25 °C. If the initial concentration of A ([A]◦
nydimaria [60]

The concentration of A will be <em>0.34 mol·L⁻¹</em> after 60 min.

In a first-order reaction, the formula for the amount remaining after <em>n</em> half-lives is

\text{[A]} = \frac{\text{[A]}_{0}}{2^{n}}\\

If t_{\frac{1}{2}} = \text{20 min}\\

n = \frac{t}{t_{\frac{1}{2}}} = \frac{\text{60 min}}{\text{20 min}}= \text{3.0}

∴ \text{[A]} = \frac{\text{2.7 mol/L}}{2^{3.0}} = \frac{\text{2.7 mol/L}}{8.0} = \textbf{0.34 mol/L}
