Quick Reference Cheat‑Sheet (Selected Core Equations) Below is a concise list you can copy onto a notecard for rapid recall while solving problems from Rao’s book.
| Category | Equation | Description | |----------|----------|-------------| | | ΔU = Q – W | Internal energy change equals heat added minus work done by the system. | | Enthalpy | H = U + pV | Useful for constant‑pressure processes. | | Second Law (Clausius Inequality) | ∮δQ/T ≤ 0 | Equality for reversible cycles. | | Gibbs Free Energy | G = H – TS | Minimum at constant T, p; ΔG = 0 at equilibrium. | | Ideal Gas EOS | pV = nRT | Basis for many derivations. | | Van der Waals EOS | (p + a/(V_m²))(V_m – b) = RT | a, b = attraction & co‑volume parameters. | | Fugacity (Real Gas) | f = φ p, ln φ = ∫(Z – 1)/p dp | φ = fugacity coefficient, Z = compressibility factor. | | Activity Coefficient (Margules 2‑suffix) | ln γ₁ = A·x₂², ln γ₂ = A·x₁² | A = binary interaction parameter. | | Bubble‑Point (binary) | y_i = K_i x_i, ∑ y_i = 1 | K_i = K‑value = φ_i^L/φ_i^V·(p_i^sat/p). | | Flash Calculation (overall) | F = L + V, z_i F = x_i L + y_i V | Material balances for overall, component, and energy. | | Equilibrium Constant (reaction) | K = ∏ (a_i)^ν_i | a_i = activity of species i. | | Exergy (Closed System) | B = (U – U₀) + p₀(V – V₀) – T₀(S – S₀) | Maximum useful work relative to environment (p₀, T₀). | 9. Final Thoughts Y. V. C. Rao’s Chemical Engineering Thermodynamics remains a practical, exam‑friendly, and concept‑solid text for undergraduate chemical engineering programs, especially in India. Its blend of theory, worked examples, and application sections makes it a reliable companion for both learning and revision. | Resource | Focus | Access | |----------|-------|--------|
