Answer

Explanation:

Step1: Define dynamic equilibrium

Dynamic equilibrium occurs when forward and reverse processes happen at equal rates.

Step2: Identify the phase changes

The forward process is sublimation ($s \rightarrow g$) and the reverse is solidification ($g \rightarrow s$).

Step3: Apply equilibrium condition

At equilibrium, the rate of sublimation must equal the rate of solidification. $$Rate_{sublimation} = Rate_{solidification}$$

Answer:

The rate of sublimation of the $NH_{4}Cl$ crystals is equal to the rate of solidification of the $NH_{4}Cl$ vapors.
