  Keq = e- G/RT = e-(62300/(8.3143)(298)) = 1.2 10-11. ... Students may use a calculator for this part (55 minutes). Part B (40 minutes) is the three reactions question (predict the products of a reaction, balance, and answer a short question regarding the reaction) and the two theory questions. A laboratory question could be in either part A or ...

  Keq=[CO] [H2O] / [CO2] [ H2] = 4.40 = X2 / (0.214-X)2. For this equilibrium, Keq=4.40, which is certainly NOT less than initial concentrations, so the assumption that X will be small is no longer valid. However, there is another algebraic simplification: Take the square root of both sides of the equation above, to give.

  and, at equilibrium , where Keq is the equilibrium constant. We will build a model of this reaction calculating how the amounts of A and B have changed after each step. The model will include the amounts the two types of particles (A and B), and two rate constants (k1 and k2).

  You will be bringing your calculator to class every day; this isn’t an option. The preferred type of calculator for Chem II is the Texas Instruments® TI-30. It’s inexpensive (about $10 at Wal-Mart or Office Max/Depot), yet powerful enough to handle anything you’ll encounter in Chem II or Physics.

  If Trial Keq = Keq , the reaction will not shift at all. (It is already at equilibrium and no macroscopic properties, like concentration will change unless the equilibrium is disturbed.) Let's do an example: For the equilibrium reaction: CO(g) + H2O(g) CO2(g) + H2(g) The value of Keq …
