Consider the reaction 2 COF2 (g) ⇌ CO2 (g) + CF4 (g) Kc = 2.00 at 1000 °C. A pure sample of COF2 is heated to 1000 °C in an evacuated container and allowed to reach equilibrium. At equilibrium, [CF4 ] is 0.266 M. What percentage of the original sample of COF2 decomposed to reach equilibrium? 7

f only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2 remains at equilibrium? Express your answer in M. 2. For the following reaction, Kc = 252 at 1000 K. CO (g) + Cl2 (g) ⇌ COCl2 (g) A reaction mixture initially contains a CO concentration of 0.157 M and a Cl2concentration of 0.173 M at 1000 K.

Explanation:

the answer would be a
