(a)

Interpretation Introduction

Interpretation:

It should be determined that whether or not the equilibrium will favour product over reactants under the given condition.

Concept Introduction:

Equilibrium constant: At equilibrium the ratio of products to reactants has a constant value. And it is represented by the letter K.

For a general reaction, aA+bBcC+dD .

The equilibrium constant Kc = [C]c[D]d[A]a[B]b a, b, c and d are the stoichiometric coefficients of reactant and product in the reaction. Concentration value for solid substance is 1.

If the value of K>1 then the reaction will be product-favoured which means product predominates at equilibrium.

If the value of K<1 then the reaction will be reactant-favoured which means reactant predominates at equilibrium.

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by ΔG. The expression for the free energy change with respect to the Keq is written below,

 ΔG=-RTlnKeq where, R is the gas constant, T is the temperature in Kelvin.

The equilibrium constant Kc = [C]c[D]d[A]a[B]b    a, b, c and d are the stoichiometric coefficients of reactant and product in the reaction. Concentration value for solid substance is 1.

If the value of K<1 then the reaction will be reactant-favoured which means reactant predominates at equilibrium.

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by ΔG. The expression for the free energy change with respect to the Keq is written below,

 ΔG=-RTlnKeq  where, R is the gas constant, T is the temperature in Kelvin.

Interpretation:

It should be determined that whether or not the equilibrium will favour product over reactants under the given condition.

Concept Introduction:

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by ΔG. The expression for the free energy change with respect to the Keq is written below,

 ΔG=-RTlnKeq  where, R is the gas constant, T is the temperature in Kelvin.

If ΔG<0 then the reaction is spontanous in forward reaction and so the reaction will favor products.

If ΔG>0 then the reaction is spontanous in backward reaction and so the reaction will favor reactants.

If ΔG=0 then the reaction is at equilibrium.

(d)

Interpretation Introduction

Interpretation:

It should be determined that whether or not the equilibrium will favour product over reactants under the given condition.

Concept Introduction:

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by ΔG. The expression for the free energy change as a function of  entropy ΔS and enthalpy ΔH, is written below,

 ΔG=ΔHTΔS  where, T is the temperature in Kelvin.

If ΔG<0 then the reaction is spontanous in forward reaction and so the reaction will favor products.

If ΔG>0 then the reaction is spontanous in backward reaction and so the reaction will favor reactants.

If ΔG=0 then the reaction is at equilibrium.

An exothermic process is one that loses heat to the surroundings.

An endothermic reaction is one that gains heat from the surroundings.

Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) CH,CN H₂O B 88 C Use these sketches to answer the questions in the table below. The enthalpy of solution AH is negative soln when CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. Would heat be absorbed or released if the system moved from Stage C to D? What force would oppose or favor the system moving from Stage C to D? Check all that apply. 1 absorbed O released neither absorbed nor released. none O ionic bonding force covalent bonding force…
