\( \mathrm{I}_{2}(\mathrm{~g})+\mathrm{Cl}_{2}(\mathrm{~g}) \leftrightarrow 2 \mathrm{ICl}(\mathrm{g}) \mathrm{Kp}=81.90 \) at \( 298 \mathrm{~K} \quad \Delta \mathrm{H}=-9.9 \mathrm{~kJ} / \mathrm{mo} \) 1. If \( \mathrm{ICl}(\mathrm{g}) \) is removed from the after its settled into equilibrium, how will the reaction respond to re-establish equilibrium? A) It will move towards reactants B) It will move towards products
