  • The rate constant of a reaction is <img alt="\mathrm{2.5 \times 10^{-4} \mathrm{~mol\, L}^{-1} \mathrm{~s}^{-1}}" src="https://entrancecorner.oncodecogs.com/gif.latex?%5Cmathrm%7B2.5%20%5Ctimes%201

The rate constant of a reaction is \mathrm{2.5 \times 10^{-4} \mathrm{~mol\, L}^{-1} \mathrm{~s}^{-1}}. If the initial concentration of the reactant is \mathrm{0.5 \mathrm{~mol\, L^{-1}}}, the total time (in second) required for complete conversion is?

Option: 1

1000s


Option: 2

2000s


Option: 3

3000s


Option: 4

4000s

\mathrm{ \because K=2.5 \times 10^{-4} \mathrm{~mol\, L}^{-1} \mathrm{~s}^{-1} }

By unit, it is zeroth order reaction. Completion time

\mathrm{ \begin{aligned} \tau=\frac{\left[R_0\right]}{k} & =\frac{0.5}{2.5 \times 10^{-4}} s \\\\ \tau & =\frac{10000}{5}=2000s \end{aligned} }
