Consider the reaction . The equilibrium constant of the above reaction is . If pure ammonia is left to dissociate , the partial pressure of ammonia at equilibrium is given by ( Assume that at equilibrium )
Law of Chemical equilibrium -
where A & B are the reactants, C & D are the product in balanced chemical equations.
- wherein
Kc is the equilibrium constant.
Relation between pressure and concentration -
- wherein
P is pressure in Pa. C is concentration in mol / litre. T is temperature in kelvin
Relation between Kp and Kc -
while calculating the value of Kp , pressure should be expressed in bar.
- wherein
= (number of moles of gaseous products) - (number of moles gaseous reaction)
