Calculate the heat of enthalpy for the reaction:
PCl5(g) → PCl3(g) + Cl2(g)
Use the information below.
P4(s) + 6Cl2(g) → 4PCl3(g) ΔH = -2439 kJ
4PCl5(g) → P4(s) +10Cl2(g) ΔH = 3438 kJ
Calculate the percent yield for an experiment in which 5.50 g of SOCl2 was obtained in a reaction of 5.80 g of SO2 with excess PCl5
