Chapter 6 Reaction Systems a singe chemical reaction 0 Includes concentrations pressures and temperatures of all reactants o Equilibrium position a point at which the concentration of all species remains constant Chemical Equilibrium a state at which the concentrations of the all reactants and products remain the same When products more concentrated equilibrium said to be shifted to the right when reactants more concentrated said to be shifted to the left Standard State 0 Gases 1atm 0 Solutions 1M 0 Pure Liquids and Solids the state of the respective element The activity of a species is a measure of the non ideality of its properties Activity of a species ai i 1M concentration per 1 molar or Pi1atm pressure per 1 atm Equilibrium Constant K a constant determined by the concentrations of the reactants and products 0 A ratio of the activity of the products to reactants at equilibrium 0 Can be written on either side of the equation by inverting K1 0 Always unit less 0 Always uses equilibrium concentrations never original 0 K depends only on Temp never on initial concentrations K c means a constant that is related to but not equal to original K If multiplying coefficients of chemical reaction multiply K as well Small K means mostly reactants at equilibrium large K means mostly products at equilibrium intermediate K means comparable amounts of products and reactants at equilibrium Note from PV nRT 9 Molarity PRT When finding Kc or Kp An totals moles of products total moles of reactants Reaction Quotient Q the value of the expression for K at any time during the reaction 0 If Q K you are at equilibrium if Q at K you are not at equilibrium yet To solve construct reaction table aka ICE Table
