The rate constant of the reaction A⟶BA ⟶ B is 0.6×10−30.6 \times {10}^{- 3} mole per liter per second. If the initial concentration of A is 5 M, then the concentration of B after 20 minutes is:

Options

  1. A1.08 M
  2. B3.60 M
  3. C0.36 M
  4. D0.72 M

Correct answer

D. 0.72 M

Step-by-step solution

For, Zero Order Reaction: x= K.t =0.6×10−3×20×60\begin{aligned} x & =\text{ K.t } \\ & =0.6 \times 10^{-3} \times 20 \times 60 \end{aligned}) So, (x=0.72 \mathrm{M})$
