NEET Physics Laws of Thermodynamics MCQ Question
What is the role of Gibbs energy in determining the spontaneity of a chemical reaction?
It combines enthalpy and entropy changes to assess spontaneity.
It solely measures the change in enthalpy of the reaction.
It indicates the temperature at which a reaction occurs.
It provides the total energy of the system without relation to spontaneity.
Correct Answer
Detailed Explanation
Gibbs energy, defined as G = H – TS, combines enthalpy and entropy changes to determine the spontaneity of a process, making it essential for assessing whether a reaction will occur spontaneously.
