The Thermodynamic Data For The Reactants And Products

Question 1Nitrosyl chloride formationChlorine gas, Cl2(g), reacts with nitric oxide, NO(g), to form nitrosyl chloride, NOCl(g), via the reactionCl2(g)+2NO(g)⇌2NOCl(g)The thermodynamic data for the reactants and products in the reaction are given in the following table: Substance ΔG∘f (kJ/mol)Cl2(g) 0NO(g) 86. 71NOCl(g) 66. 30Part AUsing standard free energy of formation values given in the introduction, calculate the equilibrium constant Kp of the reactionCl2(g)+2NO(g)⇌2NOCl(g)The standard free energy of the reaction represents the drive the reaction has under standard conditions to move toward equilibrium from point A to point X in the diagram. Express the equilibrium constant numerically using three significant figures. I have attached the diagram along with this. Question 2CaO can be used as a drying agent. One such application occurs when water is added to dry concrete or cement. The reaction that occurs isCaO(s)+H2O(l)⇌Ca(OH)2(s)The product is commonly called slaked lime. Assuming the commonly used standard-state temperature of 25∘C, calculate ΔStotal for this reaction using table from the table below. Substance S∘ [J/(K⋅mol)] ΔH∘f (kJ/mol)CaO(s) 39. 9 −635. 1H2O(l) 69. 9 −285. 8Ca(OH)2(s) 83. 4 −986. 1Express your answer to three significant figures and include the appropriate units.
