Question

a solution in which the rates of crystallization and dissolution are the same has reached tranquility dewpoint station dynamic equilibrium superstability

Explanation:

In a solution, when the rates of crystallization (solid - formation) and dissolution (solid - going into solution) are equal, it is in a state of dynamic equilibrium. The forward and reverse processes occur at the same rate, and there is no net change in the amount of dissolved and undissolved substance over time. Tranquility is not a relevant term in this context. Dew - point station is related to meteorology and not to solution processes. Superstability is not the correct term for this equal - rate condition.

Answer:

C. dynamic equilibrium
