Solution: Calculate the value of the equilibrium constant K for the hypothetical reaction2D → A + 2Bfrom the following information:A + 2B → C   Kc = 3.3C → 2D       Kc = 0.041  

Solution: Calculate the value of the equilibrium constant K for the hypothetical reaction2D → A + 2Bfrom the following information:A + 2B → C   Kc = 3.3C → 2D       Kc = 0.041  

Problem

Calculate the value of the equilibrium constant K for the hypothetical reaction

2D → A + 2B

from the following information:

A + 2B → C   K= 3.3

C → 2D       K= 0.041

 

 

Solution

Similar to Hess's Law, we must manipulate the given equations and Kc values to get the overall equation 2D → A + 2B.
