le chateliers principle

if a system in equilibrium is subjected to a change, the position of equilibrium will move in the direction which opposes that change

what value do all reactions at equilibrium have

a kc valu

what is a kc value based on

concentrations of all reactants and products

kp

equilibrium constant that only involve pressure exerted by the gas molecules

what do kp expressions only contain

the gases present in the equilibrium mixture

what is the only factor that affects the value of an equilibrium constant

temperature

if the temperature change caused equilibrium to shift right, what will happen to kp


increase

what will happen to kp if the temperature change causes equilibrium to shift left

decrease

what is the partial pressure of a gas in a gas mixture

the contribution that gas makes toward the total pressure

what is the partial pressure of each gas proportional to

its mole fraction

partial pressure=

mole fraction of gas x total pressure

mole fraction of a gas =

moles of that gas in mixture/total number of moles of gas in mixture
