07:32The equilibrium 2 NO(π) + Cl2(π) β 2 NOCl(π) is established at 500.0 K. An equilibrium mixture of the three gases has partial pressures of 0.095 atm, 0.171 atm, and 0.28 atm for NO, Cl2, and NOCl, respectively. (b) If the vessel has a volume of 5.00 L, calculate Kc at this temperature.
Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: PCl3(π) + Cl2(π) β PCl5(π). A 7.5-L gas vessel is charged with a mixture of PCl3(π) and Cl2(π), which is allowed to equilibrate at 450 K. At equilibrium the partial pressures of the three gases are πPCl3 = 0.124 atm, πCl2 = 0.157 atm, and πPCl5 = 1.30 atm. (a) What is the value of πΎπ at this temperature?
A mixture of 0.2000 mol of CO2, 0.1000 mol of H2, and 0.1600 mol of H2O is placed in a 2.000-L vessel. The following equilibrium is established at 500 K: CO2(π) + H2(π) β CO(π) + H2O (π) (d) Calculate πΎπ for the reaction.
(b) What condition must be satisfied so that Qc = Kc?
(a) If Qc > Kc, how must the reaction proceed to reach equilibrium?
(b) At the start of a certain reaction, only reactants are present; no products have been formed. What is the value of Qc at this point in the reaction?
