Question: Consider the reaction 2 COF2(g) = CO2(g) + CF4(g) at 1000 degrees Celsius in a 5.00-L container.

Use the quadratic equation to determine the equilibrium concentrations of all reactants and products if the initial amounts are 0.105 mol COF2, 0.220 mol CO2, and 0.055 mol CF4. The value of the equilibrium constant for the reaction is 2.00 at 1000 degrees Celsius.

#### Solution Preview

Find all initial concentrations first:

[COF2] = 0.105mol/5L = 0.021M
[CO2] = 0.220mol/5L = 0.044M
[CF4] = 0.055mol/5L = 0.011M

Set up the table with equilibrium ...
