QJEEM24Cha19b: JEE Main 2024 Chemistry - Class 11 JEEM24Cha19b Solution: If 5 moles of an ideal gas expands from 10   L to a volume …

If 5 moles of an ideal gas expands from 10 L to a volume of 100 L at 300 K under isothermal and reversible condition then work, w, is −x J. The value of x is __________.

(Given R = 8.314 J K−1 mol−1)

Step-by-Step Verified Solution

It is isothermal reversible expansion, so work done negative

W=−2.303nRTlog⁡(V2 V1)=−2.303×5×8.314×300log⁡(10010)=−28720.713 J≡−28721 J
