Solution: For A + 2B → 2C  Kc= 2.79                    For 2C → D  Kc= 0.106Calculate the value of the equilibrium constant for the reaction:D → A + 2BKc=?

Solution: For A + 2B → 2C  Kc= 2.79                    For 2C → D  Kc= 0.106Calculate the value of the equilibrium constant for the reaction:D → A + 2BKc=?

Problem

For A + 2B → 2C  Kc= 2.79

                    For 2C → D  Kc= 0.106

Calculate the value of the equilibrium constant for the reaction:

D → A + 2B

Kc=?

Solution

So our first goal here is to set up the first 2 given reactions so that when we add them up, it will result in the reaction below. 


So we look at them 1 at a time.
