Given : $\log 3=0.48$
$A.$ Reaction completes in $1000\,s$.
$B.$ The reaction has a half-life of $500\, s$.
$C.$ The time required for $10\, \%$ completion is 25 times the time required for $90 \,\%$ completion.
$D.$ The degree of dissociation is equal to $\left(1-e^{-k t}\right)$.
$E.$ The rate and the rate constant have the same unit.

$\mathop {{H_2}(Pt)}\limits_{1\,atm} \left| {\begin{array}{*{20}{c}}

What is the value of $x$ ? ........... $\mathrm{M}$
( give : $E_{A{g^ + }|Ag}^o = + 0.8$ $\frac{{2.303\,RT}}{F} = 0.06 $)
