Question

Which of the following is an example of solid-liquid equilibrium?

(a) water and steam at hundred degrees centigrade

(b) water and ice at 0-degree centigrade

(c) the point where Ammonia is sublimized

(d) boiling point of water

The question was posed to me in class test.

Asked question is from Equilibrium in Physical Processes topic in division Equilibrium of Chemistry – Class 11

Answer 1

Right answer is (b) water and ice at 0-degree centigrade

To explain I would say: At zero degree centigrade, when water and ice are together the opposing process occurs simultaneously at the same rate, so the amount of Ice and water remains constant. It is an example of a solid-liquid equilibrium.
