Q74 / 180 · NEET 2015 (Phase 2) · Chemistry
The rate constant of the reaction is mole per liter per second. If the initial concentration of A is 5 M, then the concentration of B after 20 minutes is:
- A1.08 M
- B3.60 M
- C0.36 M
- Correct answerD0.72 M
Solution
For, Zero Order Reaction:
\(\begin{aligned}
x & =\text { K.t } \\
& =0.6 \times 10^{-3} \times 20 \times 60
\end{aligned}\)
So, \(x=0.72 \mathrm{M}\)
Hence, the correct answer is option: 'D'.
