Consider the following exothermic equilibrium reaction. For each change, indicate whether it would cause the reaction to shift to the right (products), to the left (reactants), or have no effect. 4 HCl(g) + O2(g) ⟺ 2 H2O(l) + 2 Cl2(g)

[ Select ]

2. HCl is added?
[ Select ]

3. Cl2 is removed?
[ Select ]

4. the temperature is decreased?
[ Select ]

5. Ne (neon) is added?
