Document Summary

You can also use k to calculate the partial pressure of a species at the larger the k, the more stable the products are at equilibrium intermediate values favor neither reactants or products equilibrium. Increasing the pressure by itself will not shift the reaction. rather, an increase in volume will shift the reaction. Usually one would increase pressure by decreasing the volume. This will have a direct impact on the concentration of gases. On the other hand, when you add inert gas, you are not doing anything to the volume, thus you will not change the reaction. Chemical equilibrium cont. to determine the direction a reaction will proceed: Kc=1. 80, all three compounds are gases at 250 degrees c the balanced reaction will be: pcl5(g) pcl3(g)+cl2(g) We then simplify this equation to get x2+1. 80x-5. 40=0. We can then find x by using the quadratic equation.

We can restate this by saying that the rate of the forward reaction is equal to the rate of the reverse reaction. Recall that with rate we are simply defining how fast a reaction is proceeding, a speed at which the reaction proceeds. Take note that when writing an equilibrium expression, pure liquids (denoted by l or 2) and pure solids (denoted by s) are omitted. Typically we express the equilibrium by K or Kp where c and p denote either concentration or partial pressure respectively. We refer to this value of K, or Kp as an equilibrium constant For any reaction, Kc can be written as the product of the concentration of products, raised to their stoichiometric coefficients, divided by the product of the concentration of the reactants raised to their stoichiometric coefficients. See Equation (5-1) below for an example: aA(aq) + bB(aq-cC(aq) + dD(aq) (5-1) A] [B]b As mentioned before, K, or K, are equilibrium constants meaning that they will have the same value unless temperature is changed. This brings in two important ideas 1) We can perturb the equilibrium concentrations of a reaction, say [A] for instance which will cause the other concentrations to shift so that K for the reaction remains constant. 2) If we change temperature, we will either increase or decrease our value of K depending on the specific reaction we are examining. Determining K, and Equilibrium Concentrations During lecture we often discuss the idea of using ICE tables as a method for organizing and calculating concentrations of reactions as they proceed towards equilibrium. In a typical ICE table you need to know initial concentrations and the magnitude of K to determine the equilibrium concentrations. Alternatively, if you know the equilibrium concentrations for a reaction you can calculate K. For this experiment we will be examining a complex ion formation, when iron(III) ion
