Question

What will be the initial rate of reaction, if its rate constant is ${10}^{-3}{min}^{-1}$ and the concentration of reactant is $0.2-{dm}^{-3}$? How much of reactant will be converted into product in 200 minutes ?

Answer 1

Initial rate = $\frac{0.2}{{10}^{-3}}$ = $2\times {10}^{-4}$

$k=\frac{2.303}{t}log\frac{\left[A\right]}{[A-x]}$

${10}^{-3}=\frac{2.303}{200}log\frac{0.2}{[A-x]}$

$[A-x]=0.163-{dm}^{-3}$

The Amount of reactant converted to product is 0.2 - 0.163 = 0.037
