Which of the following statement(s) is/are true for ideal gas? — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

(A) Isothermal expansion: $|-w_{rev}|>|-w_{irr}|$ $\Rightarrow (-w_{rev})-(-w_{irr})>0$. \checkmark (B) Isothermal compression: $w_{rev}>w_{irr}$ (reversible requires min work). \checkmark (C) In multi-stage compression, heat rejected decreases each stage, so stage $(n-1)$ rejects more heat than stage $n$. \checkmark (D) Arrow points toward steeper adiabat $=$ increasing $\gamma$, so D is wrong. \texttimes
