Answer to Question #334280 in General Chemistry for Sofia

Question

The Δ𝐻vap of a certain compound is 10.14 kJ·mol−1 and its Δ𝑆vap is 78.22 J·mol −1·K−1.

What is the boiling point of this compound?

Answer 1

Solution:

T = ΔH / ΔS = (10140 J mol⁻¹) / (78.22 J mol⁻¹ K⁻¹) = 129.6 K

T = 129.6 K

Answer: The boiling point of this compound is 129.6 K
