Chemistry - Thermodynamics - II Question with Solution | TestHub

For the reaction $\mathrm{A}\left(\mathrm{g}\right)\rightleftharpoons \mathrm{B}\left(\mathrm{g}\right)$ at $495 \mathrm{K}$, ${\mathrm{\Delta }}_{\mathrm{r}}{\mathrm{G}}^{°}=-9.478 \mathrm{kJ} {\mathrm{mol}}^{-1}$

If we start the reaction in a closed container at $495 \mathrm{K}$ with $22$ millimoles of $\mathrm{A}$, the amount of $\mathrm{B}$ is the equilibrium mixture is ________ millimoles. (Round off to the Nearest Integer).

$\left[\mathrm{R}=8.314 \mathrm{J} {\mathrm{mol}}^{-1} {\mathrm{K}}^{-1};\ell \mathrm{n}10=2.303\right]$
