07:32A 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.
(a) If Qc < Kc, in which direction will a reaction proceed in order to reach equilibrium?
(b) What condition must be satisfied so that Qc = Kc?
(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?
At 100Β°C, the equilibrium constant for the reaction COCl2(π) β CO(π) + Cl2(π) has the value πΎπ = 2.19Γ10β10. Are the following mixtures of COCl2, CO, and Cl2 at 100Β°C at equilibrium? If not, indicate the direction that the reaction must proceed to achieve equilibrium. (a) [COCl2] = 2.00Γ10β3 π, [CO] = 3.3Γ10β6 π, [Cl2] = 6.62Γ10β6π
At 900 K, the following reaction has πΎπ = 0.345: 2 SO2(π) + O2(π) β 2 SO3(π) In an equilibrium mixture the partial pressures of SO2 and O2 are 0.135 atm and 0.455 atm, respectively. What is the equilibrium partial pressure of SO3 in the mixture?
