NEET Chemistry Chemical Equilibrium MCQ Question
Which of the following statements about the relationship between equilibrium constants and reaction spontaneity is correct?
A reaction with K < 1 indicates non-spontaneity.
A reaction with K > 1 proceeds to completion.
K can be used to determine the temperature effect on a reaction.
A reaction with K = 1 is always spontaneous.
Correct Answer
Detailed Explanation
The statement in option A is correct as it reflects that a reaction with K < 1 implies that the products are less favored at equilibrium, indicating non-spontaneity. This is supported by the context that a non-spontaneous reaction will proceed to a very small extent, resulting in minimal product formation.
