1) 1/3
2) 1/112
3) 1/33.6
4) 1/22.4

Answer 2

Answer:

The concdntration of CO₂ is 1/33.6 mol/lit.

Option 3 is right.

Explanation:

CaCO₃→CaO + CO₂

Dₙg = 1 mole

Kₚ =K₍c₎ RT ,here R= 0.0821 and T= 819k

K₍c₎=Kₚ/RT=2/(0.0821x81)=0.029

K₍c₎= [CO₂]

[CO₂]= 0.029=1/33.6 mol/lit

Therefore , the equilibrium concentration of CO₂ is 1/33.6 mol/lit
