Problem

The reaction

\mathrm{N_2O_5}

(in

\mathrm{CCl_4}

)

\rightarrow 2\mathrm{NO_2}+\frac{1}{2}\mathrm{O_2}

is first order in

\mathrm{N_2O_5}

with rate constant

6.2\times10^{-4}\text{ s}^{-1}

. What is the rate of reaction when

[\mathrm{N_2O_5}]=1.25\text{ mol L}^{-1}

? (a)

7.75\times10^{-4}\text{ mol L}^{-1}\text{ s}^{-1}

(b)

6.35\times10^{-3}\text{ mol L}^{-1}\text{ s}^{-1}

(c)

5.15\times10^{-5}\text{ mol L}^{-1}\text{ s}^{-1}

(d)

3.85\times10^{-4}\text{ mol L}^{-1}\text{ s}^{-1}
