-used when moles/liter are given
-use law of mass action

Question 2

Kp

Answer 2

-the equilibrium constant that expresses the relationship between the partial pressures of products and reactants in a gas-phase reaction at equilibrium
-used when atm is given
-Kp = Kc(RT)^Δn
-use law of mass action
