A student ran the following reaction in the laboratory at 666 K:

\[ 2\text{NH}_3 (g) \rightleftharpoons \text{N}_2 (g) + 3\text{H}_2 (g) \]

When she introduced 0.0752 moles of \(\text{NH}_3 (g)\) into a 1.00 liter container, she found the equilibrium concentration of \(\text{H}_2 (g)\) to be 0.105 M.

Calculate the equilibrium constant, \( K_c \), she obtained for this reaction.

\[ K_c = \]

This transcription provides the context of the experiment and the parameters involved. It describes a chemical equilibrium scenario where ammonia (\(\text{NH}_3\)) decomposes into nitrogen (\(\text{N}_2\)) and hydrogen (\(\text{H}_2\)). The task is to find the equilibrium constant, a value expressing the ratio of product concentrations to reactant concentrations at equilibrium under specified conditions.
