Application of Equilibrium Constant for the Reaction:

                                    C4H10(g)  <==> C2H6(g) + C2H4(g)

 

1. What is the concentration of C4H10 at equilibrium if the concentrations of C2H6 and C2H4 are both 0.014M?  Kc = 0.070. 

 

2. For the same reaction, if the initial concentration of C4H10 is 0.035M and there are no C2H6 and C2H4 present initially.  What is the equilibrium concentration of C4H10?

3. Following Q2, what is the equilibrium concentration of C2H6?

 

4. If the initial concentration of C4H10 is 0.030M, and the ones of C2H6 and C2H4 are both 0.023M.  At equilibrium, the concentration of C4H10 becomes 0.018M, what is the value of Kc of the reaction.

 

5. For the same reaction, if the initial partial pressure of C4H10 is 1.2 atm and the ones of C2H6 and C2H4 are both 0.6atm.  What is the partial pressure of C4H10 at equilibrium?  Kp =0.64.
