The equilibrium constant Kc for the Reaction:
H2(g) + CO2(g) <--> H2O(g) + CO(g) is 4.2 at 1650 C.
Initially 0.87 mol H2 and 0.87 mol CO2 are injected into a 4.9 L
flask. Calculate the concentraion of each species at
equilibrium
Solution :
Lets find out concentration of each species.
[H2]= 0.87 mol /4.9 L =0.178 M
[CO2]= 0.87 mol / 4.9 L = 0.178 M
Now we write the reaction and set up the ICE chart
         H2(g) +
CO2(g) <--> H2O(g) + CO(g)
