How would the equilibrium concentration of #H_2O# be affected by removing #H_2# from the mixture?
All other things equal, there would be a decline in
The question is likely to be talking about the thermal decomposition of
The Le Chatlier's Principle predicts that the system would respond to this change in a way as if it's trying to minimize the change's impact on the equilibrium conditions.
