(C) The molar mass of $SO_3$ is $80 \ g/mol$. Initial moles of $SO_3 = \frac{40 \ g}{80 \ g/mol} = 0.5 \ mol$. For the reaction $2SO_3 	o 2SO_2 + O_2$,let $x$ be the moles of $O_2$ formed. At $t = 10 \ min$,moles of $O_2 = \frac{3.2 \ g}{32 \ g/mol} = 0.1 \ mol$. Thus,$x = 0.1 \ mol$. The concentration of $O_2$ formed is $[O_2] = \frac{0.1 \ mol}{0.1 \ L} = 1 \ mol \ L^{-1}$. The rate of reaction is given by $\frac{d[O_2]}{dt} = \frac{\Delta[O_2]}{\Delta t} = \frac{1 \ mol \ L^{-1}}{10 \ min} = 0.1 \ mol \ L^{-1} \ min^{-1}$.

Time $t$ $(s)$	$0$	$5$	$10$	$20$	$30$
Concentration $(mol \ L^{-1})$	$160 \times 10^{-3}$	$80 \times 10^{-3}$	$40 \times 10^{-3}$	$10 \times 10^{-3}$	$3.5 \times 10^{-3}$

In the reaction $2SO_3 \to 2SO_2 + O_2$,initially $40 \ g$ of $SO_3$ is heated in a $100 \ mL$ container. If after $10 \ min$,$3.2 \ g$ of $O_2$ is formed,find the rate of reaction in $mol \ L^{-1} \ min^{-1}$.
