Answer

Brief Explanations:

At dynamic - equilibrium in a chemical reaction, the forward and reverse reaction rates are equal. For the reaction $2H_2 + O_2\rightleftharpoons2H_2O$, when equilibrium is reached, the system is in a stable state where the concentrations of reactants and products no longer change. The pressure is related to the number of moles of gas. According to Le - Chatelier's principle, the reaction will adjust to minimize changes. In this reaction, the forward reaction decreases the number of moles of gas. When equilibrium is reached, the pressure reaches its minimum as the system has adjusted to the balance between the forward and reverse reactions.

Answer:

C. The pressure will reach its minimum.
