Question

When the equilibrium constant K at 25oC for
2 O3(g) = 3 O2(g)
is calculated, using thermodynamic data(use delta G values), the value obtained is

a. ) 1.5 x 1057
b. ) 4.1 x 1028
c. ) 2.3 x 10-27
d. ) 130
e. ) 5.6 x 10-58

Answer 1

delta Go = -RTlnK
Look up values of delta Go for O3 and O2,
delta Go rxn = delta Goproducts - delta Go reactants.
