Free Energy Away from Equilibrium (18.4.3)

Question 1

• Chemical equilibrium can be thought of as a balance between the entropy of a reaction and the enthalpy of a reaction.

Answer 1

• Chemical equilibrium can be thought of as a balance between the entropy of a reaction and the enthalpy of a reaction.

Question 2

• Whenever a system is not at equilibrium, the relative amounts of reactants and products in the reaction are expressed by the reaction quotient (Q).

Answer 2

• Whenever a system is not at equilibrium, the relative amounts of reactants and products in the reaction are expressed by the reaction quotient (Q).

Question 3

• The free energy of a system is the free energy at standard state adjusted by the value of RTlnQ (ie. ∆G = ∆G° + RTlnQ).

Answer 3

• The free energy of a system is the free energy at standard state adjusted by the value of RTlnQ (ie. ∆G = ∆G° + RTlnQ).
