A container contains a solution of HCl (g) and oxygen, O2 (g). At some moment, the molarity of [HCl] is 0.222 mol / L and the molarity of oxygen [O] = 0.085 mol / L. In order for the reaction shown below to take place, the gases must be heated to 480 C.

4 HCl (g) + O2 (g) <--> 2 Cl2 (g) + 2 H2O (g) + Energy

What effect does it have on the equilibrium position if the heat is increased and if the volume is decreased?

1. Raise the temperature of the reaction vessel

2. Reduce the volume of the reactan
