Document Summary

Scanned by camscanner: le chatelier"s principle: if a chemical system at equilibrium is disturbed, the system shifts in a direction that minimizes the disturbance. * relationship between equilibrium constant & the chemical equation: > reverse the equation, invert the equilibrium constant. > multiply coefficients by a factor, raise equilibrium constant to same factor. > add 2 or more individual chemical equations to obtain overall equation, multiply corresponding equilibrium constants by each other. * equilibrium constants depend on temperature and many equilibrium problems give the temp even though it has no formal part in the calculations. * for finding equilibrium concentrations , there are 2 categories: > finding equilibrium concentrations when we know the equilibrium is constant and all but one of the equilibrium concentrations of the reactants and products. - calculate the concentration of the product using given quantities and expression for kc. - solve equilibrium expression for [x] and then substitute in appropriate values to calculate it.
