Phosphorus trichloride (PCl3) is an essential raw material in the production of oxyphosphorus compounds for commercial use such as oil and polymer additives, phosphate esters, pest control compounds, special lubricants and fire-resistant materials. Phosphorus trichloride is industrially manufactured by reacting solid white phosphorus (P4) with chlorine gas. (5 pts)
(a)Write a balanced chemical reaction for this reaction.
PCl3 (g) + Cl2 (g) <-> PCl5 (g) deltaH = – 88 kJ/mol at 25°C.
State and explain 2 steps that can be used to minimize formation of PCl5 according to the Le Châtelier’s principle.
