Consider the following reaction:
(C₂H₅)₂O(l) ⇌ (C₂H₅)₂O(g)
The ΔH and ΔS for the reaction above are 26.5 kJ/mol (6.34 kcal/mol) and 86.1 J/mol•K (20.6 cal/mol•K), respectively. Determine the values of ΔH (in kJ/mol and kcal/mol) and ΔS (in J/mol•K and cal/mol•K) for the following reaction:
(C₂H₅)₂O(g) ⇌ (C₂H₅)₂O(l)

• A. ΔH = −26.5 kJ/mol (−6.34 kcal/mol)
  ΔS = −86.1 J/mol•K (−20.6 cal/mol•K)
• B. ΔH = −26.5 kJ/mol (−6.34 kcal/mol)
  ΔS = 86.1 J/mol•K (20.6 cal/mol•K)
• C. ΔH = 26.5 kJ/mol (6.34 kcal/mol)
  ΔS = −86.1 J/mol•K (−20.6 cal/mol•K)
• D. ΔH = 26.5 kJ/mol (6.34 kcal/mol)
  ΔS = 86.1 J/mol•K (20.6 cal/mol•K)

Answer: (A)
