RULES / THINGS TO REMEMBER Flashcards
what does a larger value of Kc suggest
equilibrium is further to the right
what does a smaller value of Kc suggest
equilibrium is further to the left
Kc equation
Kc= [product]^mole x [product]^mole / [reactant]^mole x [reactant]^mole
what is Kp + Kc affected by
ONLY temp
total pressure =
sum of all partial pressures
partial pressure =
mole fraction of gas X total pressure
mole fraction =
number of moles of gas X total number of moles of gas in a mixture
Kp equation
Kp= p(prod)^mol x p(prod)^mol / p(react)^mol x p(react)^mol
what state is ONLY included in Kp calculations
ONLY include GAS in the equation
pH=
-log([H+]
[H+]=
10^-pH
Kw equation
Kw= [H+] [OH-]
Ka =
Ka= [H+] [A-] / [HA]
.:. Ka= [H+]^2 / [HA]
OR
Ka= 10^-pKa
pKa=
-log(Ka)
∆G =
∆G = ∆H - T∆S
