What is the sign of ΔS for each of the following processes? I.The separation of gaseous molecules of UF₆,into ²³⁸UF₆ and ²³⁵UF₆
At constant temperature and pressure.
II.The dissolving of I₂(s) in CCl₄(l) .

Question

Quizplus · Accepted Answer

I. The process involves the separation of gaseous molecules into two different gases, which increases the entropy. Therefore, ΔS is positive.
II. The dissolving of a solid in a liquid generally increases the disorder of the system, which results in an increase in entropy. Therefore, ΔS is positive.
