Now, for a complete equilibrium problem Consider the following general reaction: HC2H3O2 (aq) + H2O (l) ⇌ H3O+ (aq) + C2H3O2–(aq) Kc = 1.8 x 10–5 (at 25 ºC) If a solution initially contains (7.9x10^-1) M of HC2H3O2, (and no H3O+ or C2H3O2– ), what is the equilibrium concentration of H3O+ (aq) in the mixture? In the appropriate blanks, provide the equilibrium [H3O+ (aq)], in the solution, in M, to two significant figures and to the appropriate power
Consider this exothermic reaction at equilibrium: C(s) + 2H2(g) - CH2(g). Predict whether the reaction will shift left, right, or will not shift after each disturbance. Use the drop down to answer. When some H2 is removed, the reaction will When some C is added, the reaction will When the volume of the reaction mixture is decreased the reaction will When the temperature is increased, the reaction will shift right shift left not shift

Using Le Chatelier's Principle to predict the result of changing Nitrogen monoxide and ozone react to form nitrogen dioxide and oxygen, like this: The reaction is exothermic. Suppose a mixture of NO, O, NO2 and O2 has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. shift in...
