Find out the value of K_c for each of the following equilibria from the value of K_p:
CaCO₃ (s)  CaO(s) + CO₂(g); K_p = 167 at 1073 K

One of the reaction that takes place in producing steel from iron ore is the reduction of iron (II) oxide by carbon monoxide to give iron metal and CO₂.

What are the equilibrium partial pressures of CO and CO₂ at 1050 K if the initial pressure are:  

Bromine monochloride, BrCl decomposes into bromine and chlorine and reaches the equilibrium:
                      

for which  If initially pure BrCl is present at a concentration of  what is its molar concentration in the mixture at equilibrium?

At 1127 K and 1 atm pressure, a gaseous mixture of CO and CO₂ in equilibrium with solid carbon has 90.55% CO by mass
                       
Calculate K_c for this reaction at the above example.
