Reactions at Equilibrium
• If Keg is very large, the concentration of the products is much greater than the
eq
concentration of the reactants. The reaction goes to completion.
If Keg is very small, the concentration of the reactants is much greater than the
eq
concentration of the products. The reaction doesn't occur.
4. Consider the two reactions given below.
