Write the expression for Keq for the following reactions. In each case indicate whether the reaction is homogeneous or heterogeneous.


(a) N2(g) + 3 H2(g)  2 NH3(g)

Keq = PNH32 / (PN2 PH23)
Keq = (PN2) (3 PH2) / 2 PNH3   
Keq = PN2 PH23 / PNH32
Keq = 2 PNH3 / ((PN2) (3 PH2))
homogeneous or heterogeneous.
 
 
(b) 4 HCl(g) + O2(g)  2 H2O(l) + 2 Cl2(g)
Keq = PHCl4 PO2 / PCl22
Keq = 2 PCl2 / (4 PHCl PO2)    
Keq = 4 PHCl PO2 / 2 PCl2
Keq = PCl22 / (PHCl4 PO2)
