Chapter 14.1, Problem 2CP

In the same reaction:

${\text{F}}_2(g)+2{\text{ClO}}_2(g)\to 2{\text{FClO}}_2(g)$

if the concentration of F₂ is changing at a rate of $0.026M/s$, what is the rate of change in the concentration of ${\text{ClO}}_{\text{2}}$ ?

$\begin{array}{l}\text{a)}\hfill \\ \text{0}\text{.026 }M/s\hfill \\ \text{b)}\hfill \\ \text{0}\text{.052 }M/s\hfill \\ \text{c)}\hfill \\ \text{0}\text{.013 }M/s\hfill \\ \text{d)}\hfill \\ \text{0}\text{.078 }M/s\hfill \\ \text{e)}\hfill \\ \text{0}\text{.004 }M/s\hfill \end{array}$
