Reversible reactions can reach equilibrium with the reaction continuing at the same rate in both directions. The exponents are the same as the coefficients in the balanced equation. If K eq is much greater than 1, the reaction will approach completion. If K eq is much less than 1, equilibrium is established before much product is formed. Each chemical reaction has a unique K eq for every temperature.
Ammonia vapor combines with oxygen to produce water vapor and nitrogen.
Write a balanced equation for this reaction at equilibrium. Write the expression for the equilibrium constant. Use this webtest to practice equilibrium calculations. If a system is in equilibrium and some condition changes, the system will shift to restore equilibrium. If the concentration of either of the reactants is increased, the number of collisions between reactant particles will increase.
