Thermodynamics

Question 1

Hess’s law and its application.

Answer 1

The amount of heat absorbed or evolved in the process is same wether the process is carried out in 1 step or several step. Its application is it can determine the heat of transition and determine the heat of a reactions

Question 2

1st law of thermodynamics and its limitation

Answer 2

1st law of thermodynamics states that heat energy can neither be created nor be destroyed. Its limitation is it cannot describe the evolution and absorption of heat.

Question 3

Intensive and Extensive properties.

Answer 3

Intensive properties depends upon the pressure and amount whereas extensive properties depend only upon amount

Question 4

Bond enthalpy.

Answer 4

Total energy required to break the bond of the stated..

Question 4

Exothermic and Endothermic reaction.

Answer 4

Exothermic reaction liberate hear whereas endothermic reaction absorb heat.

Question 4

Enthalpy of formation/ reaction

Question 5

Enthalpy of combustion.

Question 6

Gibs free energy
