(i)
Interpretation: The mole fractions of each species at equilibrium have to be calculated.
Concept introduction: The composition of the particular species in the reaction mixture is calculated by the mole fraction. The mole fraction is defined as the ratio of the moles of the species to the ratio of the total moles present in the reaction mixture. The mole fraction is unit less.
(ii)
Interpretation: The value of
Concept introduction: The equilibrium constant for a reaction is abbreviated as
(iii)
Interpretation: The value of
Concept introduction: The Gibbs free energy of the reaction is the key factor of the identification of the direction of spontaneity of the reaction. For the reaction to be spontaneous, the Gibbs free energy of the reaction must be negative.
