When alcohol $\left({\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\right)$ and acetic acid are mixed together in an equimolar ratio at $27 °\mathrm{C}, 33 \%$ is converted into ester. The ${\mathrm{K}}_{\mathrm{c}}$ for the equilibrium:

${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{\ell }\right)+{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{\ell }\right)\rightleftharpoons {\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5\left(\mathrm{\ell }\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{\ell }\right)$.

Given the following reaction at equilibrium,  ${\mathrm{N}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\left(\mathrm{g}\right)\rightleftharpoons 2{\mathrm{NH}}_3\left(\mathrm{g}\right)$ . Some inert gas at constant pressure is added to the system. Predict which of the following facts will be affected?

For the reaction  ${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)\rightleftharpoons 2\mathrm{HI}\left(\mathrm{g}\right)$

${\mathrm{K}}_{\mathrm{c}}=66.9$ at $350°\mathrm{C}$ and ${\mathrm{K}}_{\mathrm{c}}=50.0$ at $448°\mathrm{C}$. The reaction has:
