Chemical equilibrium
1- Carbonyl fluoride, COF2 , 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)?CO2 (g)+CF4 (g), K c =5.60
If only COF2 is present initially at a concentration of 2.00 M , what concentration of COF2 remains at equilibrium?
2- Consider the reaction
CO(g)+NH3 (g)?HCONH2 (g), K c =0.730
If a reaction vessel initially contains only CO and NH3 at concentrations of 1.00 M and 2.00 M , respectively, what will the concentration of HCONH2 be at equilibrium?
Express your answer with the appropriate units
3- The following reaction was carried out in a 2.50L reaction vessel at 1100 K :
C(s)+H2O(g)?CO(g)+H2(g)
If during the course of the reaction, the vessel is found to contain 5.25mol of C , 13.8mol of H2O , 3.20mol of CO , and 8.60mol of H2 , what is the reaction quotient Q ?
