equilibrium constant pressure Flashcards
what is Kp?
expressing the equilibrium constant in terms of partial pressures where all the substances in equilibrium mixtures are in the gas phase
what does the sum of partial pressures equal?
sum of partial pressures = total pressure
what is partial pressure?
partial pressure is the pressure each gas would exert if it was alone in the same volume
what is the symbol for partial pressure?
p (lower case)
what is the equation to work out partial pressure?
partial pressure = mole fractions x total pressure
pA = xA x P
what is the equation to work out mole fractions?
mole fraction of a = number of moles of a / total number of moles of gas
what is the expression for Kp?
Kp = ((pC)^cx(pD)^d)/((pA)^ax(pB)^b)
