entropy is defined as degree of randomness we know that entropy decreases in the following order gas > liquid > solid and greater the number of particles greater will be the entropy. 1. I2 (g) + Cl2 (g) →2ICl (g) here all are in gas phase and number of particles are also same on each side therefore , too close to decide 2. COCl2 (g) →CO (g) + Cl2 (g) since the number of gas particles increases on the product side entropy will increase. ΔS > 0 3. CH4 (g) + 2O2 (g) →CO2 (g) + 2H2O (g) here all are in gas phase and number of particles are also same on each side therefore , too close to decide 4. 4HCl (g) + O2 (g) →2H2O (g) + 2Cl2 (g) since the number of gas particles decreases on the product side entropy will decrease. ΔS < 0 5. CaCO3 (s) →CaO (s) + CO2 (g) since the number of gas particles increases on the product side entropy will increase. ΔS > 0

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)
