The Keq value for the formation of sulphur trioxide gas from sulphur dioxide and oxygen gas is 4.5. If the equilibrium concentration of oxygen was 2.0 M, determine the number of moles of sulfur trioxide originally present in a 1.0 L vessel. [16 mol] 2 SO2(g) + O2(g) ⇌ 2 SO3(g) Keq=4.5 V=1.0L

The value of the Trial Keq (initial concentrations) is then compared with the value for Keq (at equilibrium). If Trial Keq < Keq the reaction will shift to the right. (a higher [products] is needed to bring the ratio up so that it does equal Keq ) If Trial Keq > Keq the reaction will shift to the left.

Therefore, ∆Gº’glycolysis= +1,900 –2870 = -970 kJ/mol. And, Keq = e(970/RT) = e391. My Hewlett·Packard calculator had a problem when I tried to evaluate this. To help, I took the log base 10 of e391, which is 391 x log e (391 x .434 =169) and then raised 10 to this power. The final answer is 10169.

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Keq=4.40, which is certainly NOT less than initial concentrations, so the assumption that X will be small is no longer valid.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.

There are no “x”s in the table so we don’t need to make any assumptions. It is best to use your calculator to figure out the equilibrium [HA], because the [C] may or MAY NOT be insignificant. Using a calculator 0.350 –2.399 x 10-2 = 0.32601. Don’t round it off too much here. I would keep it in a memory in my calculator.
