3. Consider the following reaction where Kc 1.18 at 150K: 2HI(E)H2(g)+ 12(s) A reaction mixture was found to contain 0.0381 moles of HI, 0.0471 moles of H2, and 0.0364 moles of lz in a 1.00 L container. Is the reaction at equilibrium? And if not, what direction must it run in order to reach equiltibriurn? At equilibrium a 1.0-liter container was found to contain 0.20 mol of A, 0.20 mol of B, 0.40 mol of C, and...
