Chapter 8: Problem 63
The reaction: \(2 \mathrm{HI} \rightarrow \mathrm{H}_{2}+\mathrm{I}_{2}\), is second order and the rate constant at \(800 \mathrm{~K}\) is \(9.70 \times 10^{-2} \mathrm{M}^{-1} \mathrm{~s}^{-1}\). How long will it take for \(8.00 \times 10^{-2}\) mol/litre of HI to decrease to one-fourth of its initial concentration? a. \(587 \mathrm{~s}\) b. \(387 \mathrm{~s}\) c. \(148 \mathrm{~s}\) d. \(687 \mathrm{~s}\)
