11.9 Hmwrk 6th edition

11.9 Balance the following equations using the smallest whole- number coefficients, then write the equilibrium expression Kc for each reaction:
(a) CH4(g) + O2(g) -> CO2(g) + H2O(g)
(b) I2(g) + F2(g) -> IF5(g)
(c) NO2(g) + F2(g) -> FNO2(g)

For Kc do we simply write the expression without any actual numerical values?

Yes; since you aren't given any numerical equilibrium molar concentrations, the question just asks for you to set it up.
So basically it would be Kc = [products]/[reactants] raised to the power of their stoichiometric coefficients.
