[Answer] Under standard conditions the reversible reaction A + B → C + D has a ΔG∘ = -25 kJ/mol. What is ΔG when: T = 475 K [A] = 0.5M [B] = 0.2 M [C] = 0.2 M and [D] = 0.3 M?

Answer: -27 kJ/molThe nonstandard concentrations have lowered ΔG by 2 kJ.mol.

Under standard conditions the reversible reaction A + B → C + D has a ΔG∘ = -25 kJ/mol. What is ΔG when: T = 475 K [A] = 0.5M [B] = 0.2 M [C] = 0.2 M and [D] = 0.3 M? A) The reaction could be coupled to power an endergonic reaction with a ΔG of +6.2 kcal/ mol . B ) The reaction could be coupled to power an exergonic reaction with a ΔG of +8.8 kcal/ mol . C ) The reaction would result in a decrease in entropy (S) and an increase in the total energy content (H) of the system. In a reaction mixture containing both reactants and products each at a concentration of 1 M the reaction quotient is 1: Qc = [1]^ c [1]^ d /[1]^a[1]^ b = 1 The value of Q relative to K is a measure of the progress of the reaction toward equilibrium. At equilibrium the reaction quotient is equal to the equilibrium constant. The water gas shift reaction is a moderately exothermic reversible reaction . Therefore with increasing temperature the reaction rate increases but the co...
