Equation (12.56) shows that the numerical value of K
p
r
is related to the datum pressure used to
define m

. If the amounts of substance of reactants and products are the same then the value of K
p
is not
affected by the datum pressure (because y

of K

will be dependent on the units of pressure. Hence the value of equilibrium constant, K
