. The four substances HCl, I2, HI, and Cl2, are mixed in a
reaction vessel and allowed to reach equilibrium in the reaction: 2
HCl (g) + I2 (s) ⇌ 2 HI (g) + Cl2 (g) Certain changes (specified in
the first column in the following table) are then made to this
mixture. Considering each change separately, state the effect
(increase, decrease, no change) that the change has on the original
equilibrium value of the quantity in the second column...
