Nitrogen dioxide, $N{O}_2,$ decomposes upon heating to form nitric oxide and oxygen according to the following equation:

$2N{O}_2(g)2NO(g)+O_2(g)$

At the beginning of an experiment, the concentration of nitrogen dioxide in a reaction vessel was $0\mathrm{.}1103$mol$/$L$.$ After $64\mathrm{.}0s,$ the

concentration decreased to $0\mathrm{.}1044$mol$/$L$.$ What is the average rate of decomposition of $N{O}_2$ during this time interval in mol$/$Ls $?$
