Equilibrium 

• -  Kc = [product 1]^x [product 2]^y/[reactant] etc.

• -  X and y are the multiplying factor in terms of the molar ratio

• -  All in the equation must be homogeneous and of the same state if a heterogenous

  equation then exclude the ones of different never solids in the statement

• -  Remember unless all the same volume you need to calculate the concentration but if all

  the same volume then should be fine

• -  Remember to calculate units for Kc will always be mol dm-3 and then rearranged as

  required for the equation to do with canceling out etc.

• -  Kp units will be atm rearranged according to the equation and the squared etc.

• -  Kp system of calculation

  • -  Calculate the equilibrium moles using ICE

  • -  Add the total number of equilibrium moles

  • -  Calculate the mole fraction of every relevant term in the equation by doing

- Equilibrium moles of X/Total Moles

• -  Mole fraction value x total pressure (should be provided) = partial pressure

• -  Check: make sure all the partial pressures equal the total pressure

• -  The fit the partial pressures into the equilibrium kP statement and calc Kp

• -  Units calc
