Part $2(0\mathrm{.}3$ point$)$

If the rate constant for the reaction is $1\mathrm{.}31{10}^4{M}^{-1}{s}^{-1}$ at $298K.$ What is the rate of the reaction when $[N{O}_2]=2\mathrm{.}13{10}^{-8}{M}^{-1}$ and $[O_3]=1\mathrm{.}23{10}^{-7}M?$

$10\frac{M}{s}$larr

Part $3(0\mathrm{.}3$ point$)$

What is the rate of the appearance of $N{O}_3$ under these conditions?

$IC\frac{M}{s}-$
