JEE Main 2026 Chemistry question
Match the LIST-I with LIST-II
List-I (Thermodynamic Process): (A) Work done in reversible, isothermal expansion of 2 mol of ideal gas from 2 dm³ to 20 dm³ at 300 K. (B) Work done in irreversible isothermal expansion of 1 mol ideal gas from 1 m³ to 3 m³ at 300 K against a constant pressure of 3 kPa. (C) Change in internal energy for adiabatic expansion of a 1 mol ideal gas with change of temperature = 320 K and . (D) Change in enthalpy at constant pressure of 1 mole ideal gas with change of temperature = 337 K and .
List-II (Magnitude in kJ): (I) 4 (II) 11.5 (III) 6 (IV) 7
Choose the correct answer from the option given below:
Answer: (2)
Solution
(A) kJ (II); (B) kJ (III); (C) kJ (I); (D) kJ (IV).
