Solution: Nitrogen gas can spontaneously combine with hydrogen gas to create hydrazine based on the following reaction:                                                  N     2 (g)  +  2 H2 (g) ⇌ N2H4 (g)                                     What is the Kc for the forward reaction if the equilibrium concentrations of N 2, H2 and N2H4 are 0.800 atm, 0.500 atm and 0.010 atm respectively at 25oC ? 

Problem

Nitrogen gas can spontaneously combine with hydrogen gas to create hydrazine based on the following reaction:

                                                 N     2 (g)  +  2 H2 (g) ⇌ N2H4 (g)                                    

What is the Kc for the forward reaction if the equilibrium concentrations of N 2, H2 and N2H4 are 0.800 atm, 0.500 atm and 0.010 atm respectively at 25oC ?
