In a 1.0 L container there are, at equilibrium, 0.20 mole of I2, 0.30 mole of H2 and 0.20 mole of HI. What is the value of Kc for this reaction? H2(g)  +  I2(g)  ↔  2HI(g) :  reaction is in equilibrium “↔”  Kc = [HI]2 / { [H2] X [I2]} 

When the following reaction is balanced the coefficients in front of the reactants and products are:  H2X(aq) + NaOH = Na2X(aq) + H2O(l)
