Chemical equilibrium 2
1- Carbonyl fluoride, COF 2 , is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF 4 via the reaction
2COF 2 (g)â‡ŒCO 2 (g)+CF 4 (g), K c =5.60
If only COF 2 is present initially at a concentration of 2.00 M , what concentration of COF 2 remains at equilibrium?
2- Consider the reaction
CO(g)+NH 3 (g)â‡ŒHCONH 2 (g), K c =0.730
If a reaction vessel initially contains only CO and NH 3 at concentrations of 1.00 M and 2.00 M , respectively, what will the concentration of HCONH 2 be at equilibrium?

3- The following reaction was carried out in a 2.50L reaction vessel at 1100 K :
C(s)+H 2 O(g)â‡ŒCO(g)+H 2 (g)
If during the course of the reaction, the vessel is found to contain 5.25mol of C , 13.8mol of H 2 O , 3.20mol of CO , and 8.60mol of H 2 , what is the reaction quotient Q ?
Enter the reaction quotient numerically.
