NEET Physics Laws of Thermodynamics MCQ Question
What is the condition for a process to be spontaneous according to the laws of thermodynamics?
If ∆G is negative (< 0), the process is spontaneous.
If ∆G is positive (> 0), the process is spontaneous.
If ∆G is zero, the process is spontaneous.
If ∆G is undefined, the process is spontaneous.
Correct Answer
Detailed Explanation
A spontaneous process occurs when the change in Gibbs free energy (∆G) is negative, indicating that the process can occur without external influence. This is directly mentioned in the context provided.
