Answer 1

Hi,

Hope you are doing well.

PART A:

We know that, Change in Gibbs free energy,

Where,

'' is the Change in Gibbs free energy. (J)

'' is the Change in enthalpy of the reaction. (J)

'' is the Temperature at which the reaction occurs. (K)

'' is the Change in entropy of the reaction. (J/K)

Given that,

Change in enthalpy of the reaction,

Temperature at which the reaction occurs,

Change in entropy of the reaction,

Change in Gibbs free energy,

PART B:

We have, Change in Gibbs free energy,

Given that,

Change in enthalpy of the reaction,

Temperature at which the reaction occurs,

Change in entropy of the reaction,

Change in Gibbs free energy,

PART C:

We have, Change in Gibbs free energy,

Given that,

Change in enthalpy of the reaction,

Temperature at which the reaction occurs,

Change in entropy of the reaction,

Change in Gibbs free energy,

PART D:

We have, Change in Gibbs free energy,

Given that,

Change in enthalpy of the reaction,

Temperature at which the reaction occurs,

Change in entropy of the reaction,

Change in Gibbs free energy,

PART E:

We know that, According to thermodynamics,

FOR A REACTION TO BE SPONTANEOUS ,ITS VALUE MUST BE NEGATIVE.

In PART A, we have Gibbs free energy,

SINCE THE SIGN OF IS NEGATIVE, THE REACTION GIVEN IN PART A IS SPONTANEOUS.

PART F:

We know that, According to thermodynamics,

FOR A REACTION TO BE SPONTANEOUS ,ITS VALUE MUST BE NEGATIVE.

In PART B, we have Gibbs free energy,

SINCE THE SIGN OF IS POSITIVE, THE REACTION GIVEN IN PART B IS NOT SPONTANEOUS AT .

PART G:

We know that, According to thermodynamics,

FOR A REACTION TO BE SPONTANEOUS ,ITS VALUE MUST BE NEGATIVE.

In PART C, we have Gibbs free energy,

SINCE THE SIGN OF IS POSITIVE, THE REACTION GIVEN IN PART C IS NOT SPONTANEOUS AT .

PART H:

We know that, According to thermodynamics,

FOR A REACTION TO BE SPONTANEOUS ,ITS VALUE MUST BE NEGATIVE.

In PART D, we have Gibbs free energy,

SINCE THE SIGN OF IS NEGATIVE, THE REACTION GIVEN IN PART D IS SPONTANEOUS AT .
