Classify the following solutions as saturated, unsaturated, or supersaturated, based on your graph. Note that c. and d. require you to convert from the concentrations give to g/100 g H2O before you refer to the graph.
the reaction must progress forward to attain equilibrium. The richer a reaction mixture is in product the higher its Q value is. The value of K does not change as a reaction progresses toward equilibrium.
