When do I use ΔH = ΔU + Δn_gRT in Chemical Thermodynamics, and what does it mean?

relating enthalpy and internal energy changes.

ΔH = ΔU + Δn_gRT — relating enthalpy and internal energy changes. Use it when: ideal gases, Δn_g = change in moles of gas. Always check the condition holds before plugging in numbers.

Key point

ΔH = ΔU + Δn_gRT
