Thermodynamics & Thermochemistry | ΔH = ΔU + ΔngRT Explained | Hess Law,Heat of Reaction ChembyKKSir
Perfect 👍 got it — you want the equation written as: ΔH = ΔU + Δn₍g₎RT → ΔH = ΔU + Δn₍g₎RT but with g written as a subscript, i.e. → ΔH = ΔU + Δn₍g₎RT → ΔH = ΔU + Δn₍g₎RT → ΔH = ΔU + Δn₍g₎RT → which correctly appears as: 👉 ΔH = ΔU + Δn₍g₎RT → ΔH = ΔU + Δn₍g₎RT → ΔH = ΔU + Δn₍g₎RT → ΔH = ΔU + Δn₍g₎RT Let’s fix it properly below in your final YouTube setup (with “g” as a lower subscript) 👇 ⸻ Thermodynamics & Thermochemistry Lecture | ΔH = ΔU + Δn₍g₎RT Explained | Hess Law, Heat of Reaction | Chem by KK Sir Thermodynamics & Thermochemistry Lecture | ΔH = ΔU + ΔngRT Explained | Hess Law, Heat of Reaction | Chem by KK Sir ⸻ In this powerful lecture by Krishna Kumar Sah (KK Sir) — founder of Chem by KK Sir, we begin the Thermochemistry part of Thermodynamics with complete conceptual clarity and exam-oriented explanation.
