For any chemical reaction at equilibrium, increasing the amount of any ingredient will drive the reaction in the other direction. Glucose, for example, can exist in two isomeric forms, alpha and beta, which are spontaneously interchangeable. When dissolved in water, these forms come into balance, such that 1/3 of the glucose is alpha and 2/3 is beta. Thus: alpha glucose <---> beta glucose. 1. If you start by dissolving alpha glucose in water to a concentration of 1M: a. What will the concentration of alpha glucose be after equilibrium is attained? b. What will the concentration of beta glucose be? c. What would have happened if you began with 1M of beta glucose?
