Verified Solution

Answer & Solution

Correct Answer

(C) \(4281\)

Step-by-step Solution

Detailed explanation

In the reaction \({A_2} \leftrightarrow 2A\) Initially, Let \([{A_2}] = 1\,M\) and \([A] = 0\,M\) After \(20\%\) dissociation , \(80\%\) of \(A_2\) remains. \([{A_2}] = 1 \times \frac{{80}}{{100}} = 0.8\,M\) \(20\%\) of \(1\,M\) is…
