Solution 1

To calculate the change in entropy (ΔS), we can use the formula:

ΔS = ΔH/T

where ΔH is the change in enthalpy and T is the absolute temperature.

Given in the problem, we have:

ΔH = 4.60 kJ/mol = 4600 J/mol (since 1 kJ = 1000 J) T = 158.7 K

Substituting these values into the formula, we get:
