JEE Main 2024 — Chemical Equilibrium Question with Solution

JEE Main 2024 (31 Jan Shift 2)

Question

Ag⇌Bg+C2g. The correct relationship between KP, α and equilibrium pressure P is

Choose an option

Show full solutionCorrect option: B
Correct answer
BKP=α32P122+α121−α

Step-by-step explanation

Ag⇌Bg+12Cgat t=0100at eq.1-ααα2

Total moles at equilibrium: =1-α+α+α2=1+α2

PB=α1+α2p       Pc=α21+α2p      PA=1-α1+α2p

Kp=PB×PC12PA=α1+α2pα21+α2p121-α1+α2p

 Kp=α32p12212(1-α)1+α212

Kp=α32p121-α2+α12
