Answer:
- C. The rate of sublimation of the NHâ‚„CI crystals is equal to the rate of solidification of the NHâ‚„CI vapors.
Explanation:
The question is garbled and the reactants and products do not match.
This is the correct question, assuming the products are correctly described:
"Consider the equilibrium system below.
       [tex]NH_4Cl(s)\rightleftharpoons NH_4Cl(g)[/tex]
If the system is at dynamic equilibrium, which statement is true?
- A. Sublimation of the NHâ‚„CI crystals stops.
- B. Solidification of the NHâ‚„CI vapors stops.
- C. The rate of sublimation of the NHâ‚„CI crystals is equal to the rate of solidification of the NHâ‚„CI vapors.
- D. The rate of sublimation of the NHâ‚„CI crystals is higher than the rate of solidification of the NHâ‚„CI vapors"
Solution
The left side of the equation shows solid NHâ‚„CI. The right side shows gas NHâ‚„CI.
Thus, the equation represents the equilibrium between the formation of crystals (solid) and vapors (gas) of the compound NHâ‚„CI.
The change from solid state to gas state is represented by the forward reaction (fom left to the right). It is named sublimation.
The change from vapors to crystals (named deposition) is represented by the reverse reaction (from right to left).
Dynamic equilibrium means that the molecules continually form vapors and cristals at the same speed. Thus, the final result is that each the total number of molecules of vapors and the total number of molecules of crystals do not change.
In conclusion, "The rate of sublimation of the NHâ‚„CI crystals is equal to the rate of solidification of the NHâ‚„CI vapors" (option C).
Answer:
It's C, the rate of sublimation of the NH4Cl crystals is equal to the rate of solidification of the NH4Cl vapors.
