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)
