Here is the LONG version of the definition. How you do it will follow.
When a system is in equilibrium, the product of the products of the reaction, divided by the product of the reactants, each raised to a power indicated by the coefficients in the balanced chemical equation, is a constant.
Here is what you do. Keq = (products)^x/(reactants)^y so
2A + B ==> 3C + D
Keq = (C)^3(D)/(A)^2(B)
(A) is read "concentration of A" and is in mols/L. Similarly for B, C, D.
Let me know if this is not clear. You write the Keq for the reaction and I'll check it for you.
Write the equilibrium expression for each of the following reactions:
N2 (g) + 3 H2 (g) ↔ 2 NH3 (g) + heat
