Problem

The first-order photodecomposition of gas B was studied at two temperatures. For each temperature, a plot of

\ln[B]

versus time (in seconds) was constructed. The slopes obtained are

-1.20\times10^{-3}\,\text{s}^{-1}

at 298 K and

-3.60\times10^{-3}\,\text{s}^{-1}

at 308 K. Which of the following gives the value of the rate constant

k

at 308 K expressed in min

^{-1}

? (a)

0.00360\;\text{min}^{-1}

(b)

0.144\;\text{min}^{-1}

(c)

0.216\;\text{min}^{-1}

(d)

0.0720\;\text{min}^{-1}
