At equilibrium, the concentrations of reactants and products canbe predicted using the equilibrium constant, Kc, which is amathematical expression based on the chemical equation. Forexample, in the reactionaA+bB cC + dDwhere a, b, c, and d are the stoichiometric coefficients, theequilibrium constant isKe=[C] [D]d[A] [B]bwhere [A], [B], [C], and [D] are the equilibrium concentrations.If the reaction is not at equilibrium, the quantity can still becalculated, but it is called the reaction quotient, Qe, instead of theequilibrium constant, Ke.Qc[C], [D]d[A],"[B],"where each concentration is measured at some arbitrary time t. At equilibrium, the concentrations of reactants and products can be predicted using the equilibrium constant, Ke, which is amathematical expression based on the chemical equation.

A common type of reaction we will study is that having a very small K value (K 1). Solving for equilibrium concentrations in an equilibrium problem usually requires many mathematical operations to be perfomed. However, the math involved when solving equilibrium problems for reactions having small K values (K 1) is simplified. What assumption is made when solving the equilibrium concentrations for reactions with small K values? Whenever assumptions are made, they must be checked for validity. In general, the 5% rule is used to check the validity of assuming x (or 2 x, 3x, and so on) is very small compared to some number. When x (or 2 x. 3x. and so on) is less than 5% of the number the assumption was made against, then the assumption is said to be valid. If the 5% rule fails, what do you do to solve for the equilibrium concentrations?
