General Chemistry II Assignment 2 Due at 11:00am on Tuesday, July 22, 2008 View Grading Details The Equilibrium Constant Expression Learning Goal: Understand the form and meaning of the equilibrium constant expression. Chemical reactions are usually not one-way trips from reactant to product. In fact, most chemical reactions are reversible to at least some extent. In other words, products formed by the forward reaction may react with each other to regenerate the reactants. When reactants are mixed, they will begin to react at a forward reaction rate particular to that chemical reaction. As reactants are depleted and products are formed, however, the rate of the forward reaction begins to slow, and the rate of the reverse reaction begins to increase. Eventually, the forward and reverse reaction rates will be identical. The products of the reaction are being formed at the same rate as they are being converted back to reactant, and there is no overall change in the concentrations of the reactants or the products. At this point, chemical reactions are said to be at
