Sample Problem 17.3
SOLUTION:
Determining the equilibrium constant for an equation multiplied by a common factor
the equilibrium constant, Kc, is 2.4 x 10-3 at 1000 K. If we change the coefficients of the equation, which we’ll call the reference (ref) equation, what are the values of Kc for the following balanced equations?
(a) The reference equation is multiplied by 1/3, so Kc(ref) will be to the 1/3 power.
Kc = (2.4 x 10-3)1/3 = 0.13
(b) The reference equation is reversed and halved, so Kc(ref) is to the -1/2 power.
Kc = (2.4 x 10-3)-1/2 = 20.
