Question

Which is the correct equilibrium constant expression for the following reaction?

NiO(s) + H2(g) Ni(aq) + H2O(g)
 

 

 

a) 

Kc = [H2]/[H2O]

 

b) 

Kc = [Ni][H2O]/[Ni2O3] [H2]

 

c) 

Kc = [Ni] [H2O]/[H2]

 

d) 

Kc = [Ni2O3] [H2]/[Ni][H2O]

 

e) 

Kc = [H2O]/[H2]

Expert Solution
Step 1
