Equilibrium 01 Ques2
Question: In a physical equilibrium process like the vaporization of a liquid, what condition must be met at equilibrium?
Options:
A) The rate of evaporation equals the rate of condensation
B) The rate of evaporation is greater than the rate of condensation
C) The rate of condensation is greater than the rate of evaporation
D) Both rates become zero
Show Answer
Answer: a
Explanation:
A) Correct. At equilibrium in a physical process like vaporization, the rate of the forward process (evaporation) equals the rate of the reverse process (condensation).
B) Incorrect. If evaporation rate were greater, the system would not be at equilibrium.
C) Incorrect. If condensation rate were greater, the system would not be at equilibrium.
D) Incorrect. The rates do not become zero at equilibrium; they become equal but non-zero.
