CHM 101 Thermochemistry II Objective Question

Question

What is the relationship between ΔH and ΔU?
Options
A ΔH = ΔU
B ΔH = ΔU - Δ(PV)
C ΔH = ΔU + Δ(PV)
Correct Answer
D ΔH = ΔU × Δ(PV)
Correct Answer

Option C is the correct answer.

Detailed Explanation

ΔH = ΔU + Δ(PV). For reactions involving gases, ΔH = ΔU + Δn_g RT, where Δn_g is the change in moles of gas.

Hint

The notes provide this relationship.
