What happens to the concentrations of reactants and products at equilibrium? When describing/comparing K as it's own value (K < 10 -3 or K > 10 3 ), saying products/reactants are favored means that's where the equilibrium is more likely to exist - if K < 10 -3, then there are more REACTANTS at equilibrium, which means that reactants are favored at equilibrium . Chapter 18 Chemical reactions begin when the reactants come into contact and continue until at least one reactant, (the limiting So it's an endemic reaction. \(\ce{CO(g) + H_2O(g) \rightleftharpoons CO_2(g) + H_2(g)}\), \(\mathrm{K_{eq}=5.09} \,(\text{at 700 K})\).

Thus, a system in chemical equilibrium is said to be in stable state. Use equilibrium constant expressions to solve for unknown concentrations. Since the numerator would have to be greater than the denominator in this case to yeild answer greater than 1, therefore the relative product concentration would have to be greater than that of reactants. I tried googling on how it is done and the only thing that comes up is solving for the value of K. There is nothing else given except the chemical reaction itself.
