In a first order reaction with time the concentration of the reactant decreases

Options

  1. Alinearly
  2. Bexponentially
  3. Cno change
  4. DNone of these

Correct answer

B. exponentially

Step-by-step solution

For first order reaction [A]=[A0]\mathrmek∴[\mathrm{A}]=\left[\mathrm{A}_{0}\right] \mathrme^{\mathrm{k}}\therefore The concentration of reactants will exponentially decreases with time.
