A first order reaction has the rate constant, $\displaystyle \mathrm{k}=4.6 \times 10^{-3} \mathrm{~s}^{-1}$. The number of correct statement/s from the following is/are $\displaystyle \_\_\_\_$ Given: $\displaystyle \log 3=0.48$ A. Reaction completes in $\displaystyle 1000$ s. B. The reaction has a half-life of $\displaystyle 500$ s. C. The time required for $\displaystyle 10 \%$ completion is $\displaystyle 25$ times the time required for $\displaystyle 90 \%$ completion. D. The degree of dissociation is equal to $\displaystyle \left(1-\mathrm{e}^{-\mathrm{kt}}\right)$ E. The rate and the rate constant have the same unit.
