**Chemical Equilibrium Reaction**

The following reaction was performed in a sealed vessel at 795°C:

\[ \text{H}_2(g) + \text{I}_2(g) \rightleftharpoons 2\text{HI}(g) \]

Initially, only \(\text{H}_2\) and \(\text{I}_2\) were present at concentrations of \([\text{H}_2] = 3.35\,M\) and \([\text{I}_2] = 2.80\,M\). The equilibrium concentration of \(\text{I}_2\) is \(0.0900\,M\). What is the equilibrium constant, \(K_c\), for the reaction at this temperature?
