Problem

The first-order decomposition of di-

\textit{tert}

-butyl peroxide (DTBP) to acetone and ethane is given by

\mathrm{C_8H_{18}O_2(g)\longrightarrow2CH_3COCH_3(g)+C_2H_6(g)}.

The half-life of the reaction is

80\ \text{min}

147^\circ\text{C}

. Starting with pure DTBP at a pressure of

800\ \text{torr}

in a constant-volume flask maintained at

147^\circ\text{C}

, find the time at which the partial pressure of acetone becomes

1400\ \text{torr}
