How does an increase in the pressure within the container by the addition of an inert gas like helium affect the amount of the Cl2 present at equilibrium for the following reaction? 4 HCl(g) + O2(g) ? 2 H2O(g) + 2 Cl2(g) ?H° = 120 kJ How does an increase in the pressure within the container by the addition of an inert gas like helium affect the amount of the Cl2 present at equilibrium for the following reaction? 4 HCl(g) + O2(g) ? 2 H2O(g) + 2 Cl2(g) ?H° = 120 kJ The amount of Cl2 will decrease. Cannot be predicted. The amount of Cl2 will not change. The amount of Cl2 will increase.
