IIT/JEE Chemistry Practice #29: Thermodynamics

The video tutorial covers three key questions related to thermodynamics. The first question discusses the entropy changes during the vaporization of water, emphasizing the relationship between system and surroundings. The second question examines a heat engine's compliance with the first law of thermodynamics, highlighting energy conservation principles. The third question explores activation energies in endothermic reactions, comparing forward and backward reactions. The tutorial suggests reviewing classical physics and chemistry series for a deeper understanding of these concepts.

What is the significance of the change in entropy when boiling water?

Discuss the implications of the first law of thermodynamics on heat engines.

How does the activation energy for the forward reaction compare to that of the reverse reaction in an endothermic process?
