A. 4NO(g)+2O^2 <--> 2N^2O^4(g)

B. 2NO(g)+ Br^2(g) <--> 2NOBr(g)

C. CO(g)+ 2H^2(g) <--> CH^3OH(g)

D. SO^2(g) + NO^2(g) <--> SO^3(g) + NO(g)

1. What is your problem with these. Keq expressions are the same.
K = (products)^x/(reactants)^y and raise each substance to the power indicated by the coefficient.

3. No, the problem says to write the equilibrium constant expression. Nothing about finding the value of K.

4. Not the value, the equilibrium constant. DrBob222, there's no instance of the letter "K" except in your own statement
