Consider the following reaction and associated equilibrium constant at $723K$ :

$N_2(g)+3H_2(g)2N{H}_3$

$K_C=0\mathrm{.}158$

Match each of the following sets of initial concentrations below to a description on the right.

$\{\begin{array}{c}\text{:}[N_2{]}_i=0\mathrm{.}152M\end{array}$

$\{\begin{array}{c}\text{:}[H_2{]}_i=0\mathrm{.}350M\end{array}$

$\{\begin{array}{c}\text{:}[N{H}_3{]}_i=0\mathrm{.}600M\end{array}$

I. Reaction will create reactants $($move left$)$ to reach equilibrium. $.$

$[H_2{]}_i=0\mathrm{.}350M$

$[N{H}_3{]}_i=0\mathrm{.}600M$

II$.$ Reaction is already at equilibrium.

$[N_2{]}_i=0\mathrm{.}117M$

$\{\begin{array}{c}\text{:}[H_2{]}_i=9\mathrm{.}7{10}^{-2}M\end{array}$

$\{\begin{array}{c}\text{:}[N{H}_3{]}_i=1\mathrm{.}2{10}^{-3}M\end{array}$

$\{\begin{array}{c}\text{:}[N_2{]}_i=0\mathrm{.}158M\end{array}$

$\{\begin{array}{c}\text{:}[H_2{]}_i=0\mathrm{.}315M\end{array}$

$\{\begin{array}{c}\text{:}[N{H}_3{]}_i=0\mathrm{.}698M\end{array}$

III. Reaction will create products $($move right$)$ to reach equilibrium.
