Understanding Chemical Equilibrium

A chemical reaction can reach a state known as equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. At this point, the concentrations of the reactants and products remain constant over time, although both reactions continue to occur.

Consider the following equilibrium reaction:

2 H₂ (g) + O₂ (g) <=> 2 H₂O (g)

At equilibrium, if the concentration of water (H₂O) is found to be higher after the system has reached equilibrium, what can be inferred about the reaction conditions?
