What is the concentration of CH3OH if [H2] = 0.080M and [CO] = 0.025M at 700K, and **Keq **= 290? 8. Using a **Keq **value of 1.7 x 106 at 2027(C for the following reaction, what is the equilibrium concentration of nitrogen monoxide when the concentrations of nitrogen and oxygen at equilibrium are 1.8 x 10-3M and 4.2 x 10-4M, respectively?

The equilibrium constant, Kc, for the reaction will have the following expression: Several reaction mixtures will be prepared with different initial amounts of ethyl acetate and water so that an average value of the equilibrium constant can be determined. A fixed amount of 3.00M HCl will be added to each reaction mixture as a catalyst.

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Keq=4.40, which is certainly NOT less than initial concentrations, so the assumption that X will be small is no longer valid.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

Write the **Keq Expression **for this equilibrium: **Keq **= 59KJ + 2H2O(l) H3O+(aq) + OH-(aq) **Keq **= [H3O+] [OH] (liquid water left out) ... 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. BUT BECAUSE THE “0.350” IS 3 DECIMAL PLACES AND YOU ARE SUBTRACTING, THE [E ...

Equilibrium constant (Keq) The relationship between the concentration of products and reactants at equilibrium can be expressed by an equilibrium constant. [ ] denotes molar concentrations. When writing equilibrium expressions, reactants or products that are pure solids or pure liquids do not appear in the expression. 1.

You can see the the last expression: is the **Keq expression **for Equation 3. So the value of K3 (or the **Keq **for Equation 3) would be. K1 x K2 = 5.0 x 3.0 = 15. To summarize: When you add 2 equations to get a third one, the **Keq **value for the third one is the product of the Keq’s for the original equations. Questions: 1.

Partial pressures or concentrations can be used in the equilibrium constant expression. In terms of partial pressures: ... If **Keq **<< 1 we say that “reactants are favored”. A very large equilibrium constant ( >1000) means that the reaction will nearly go to completion. A very small equilibrium constant (<0.001) means very little product will ...
