CHEM 112 Study Guide - Final Guide: Equilibrium Constant, Reversible Reaction, Reaction Rate Constant
Document Summary
K is large: equilibrium concentration of products is large reaction will proceed to the right k is small: equilibrium concentration of reactants is large reaction will proceed to left. K allows us to determine reaction direction and the ratios of the concentrations of reactants to products when equilibrium is reached. 15. 5 the reaction quotient, q - predicting the direction of net. Q can have any numerical value between 0 and infinity (undefined) the composition of a system not at equilibrium will change in a way that makes q approach k. Q = k, system is at equilibrium no further change in composition of system unless conditions change. Q < k, ratio of conc. of products to conc. of reactants is less than ratio at equilibrium reaction proceeds to the right as written form products at expense of reactants. 15. 6 altering equilibrium conditions - le chatelier"s principle.
