Phosphoryl chloride, POCl3(g), is used in the manufacturing of flame retardants. It is manufactured in an equilibrium process in which phosphorus trichloride reacts with nitrogen dioxide to form POCl3(g)and NO(g) according to the following equation: PCI3 (g) + NO₂ (g) POCI3 (g) + NO (g) + 228.93kJ At 298K, the equilibrium concentration of POCI3 was 0.68 mol/L, the concentration of NO was 0.72mol/L, the concentration of PC13 was 0.62 mol/L, and the concentration of NO₂ was 0.56 mol/L. a. 6.25 moles of POCI3 (g) is added to the 5.0 L reaction chamber. What is the new concentration of POCI 3 (g) when equilibrium is re-established? PCI 3 (g) NO2 (g) E' - C E + 11 POCI 3 (g) + NO(g)
