$\Delta_{ I } G ^{\circ}=-9.478\, kJ\, mol ^{-1}$
If we start the reaction in a closed container at $495\, K$ with $22$ millimoles of $A ,$ the amount of $B$ is the equilibrium mixture is millimoles ..............
(Round off to the Nearest Integer).
$\left[ R =8.314 J mol ^{-1} K ^{-1} ; \ell n 10=2.303\right]$
$CaC{O_3}\left( s \right)\overset \Delta \longleftrightarrow CaO\left( s \right) + C{O_2} \uparrow ,{K_p} = 8 \times {10^{ - 2}}$
$C{O_2}\left( g \right) + C\left( s \right) \rightleftharpoons 2CO\left( g \right),{K_p} = 2$
