## Problem

$\ce{2NH3}(g) \rightleftharpoons \ce{N2}(g) + \ce{3H2}(g)$
At 680, space, K, 0, point, 40, space, m, o, l each of the three gases in the reaction represented above are placed in an evacuated, rigid 1, point, 0, space, L container. The value of K, start subscript, c, end subscript for the reaction at 680, space, K is 0, point, 62.
At equilibrium, which of the gases will have the highest concentration?
