Answer 1

Answer:

S ◦ (CH3Cl) < S◦ (CH2Cl2) < S◦ (CHCl3)

Answer 2

Answer:

S ◦ (CH3Cl) < S◦ (CH2Cl2) < S◦ (CHCl3)

Explanation:

Table of contents No headers Because the entropy of a substance depends on the amount of substance, the pressure, and the temperature, it is convenient to describe the entropy of a substance in terms of Sm°, its standard molar entropy, i.e., as the entropy of 1 mol of substance at the standard pressure of 1 atm

So ,

S ◦ (CH3Cl) < S◦ (CH2Cl2) < S◦ (CHCl3)
