If we start a reaction from 100 mol, having the rate constant is \mathrm{0.0693 \mathrm{~min}^{-1}}. What will be the rate of the reaction offer 20 min.

 

Option: 1

693 \mathrm{\; mol\; min^{-1}}


Option: 2

693 \mathrm{\; mol\; min^{-1}}


Option: 3

0.693 \text { mol min }^{-1}


Option: 4

\mathrm{2.5 \: mol\: min^{-1}}

\mathrm{t_{1 / x}=\frac{0.693}{k}=\frac{0.693}{0.0693}=10 \mathrm{~min}}

Reactant after 20 min = 25 mol

\mathrm{\text { Rate }\left(\frac{d A}{d t}\right)=K \mid A 3=0.0693 \times 25 \text { mol\: min}^{-1}}
