Dalton's Law states that in a mixture of gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases present. If one gas is removed from this mixture, its contribution to the total pressure is also removed. As a result, the total pressure of the gas mixture will decrease because there are fewer gas particles contributing their partial pressures to the total.

When one gas is eliminated, the remaining gases are still exerting their individual pressures, but those pressures alone will not be enough to maintain the original total pressure. Thus, the overall pressure must decrease to reflect the removal of that gas and its corresponding partial pressure.

This reduction in total pressure highlights the direct relationship between the number of gas components in a mixture and the total pressure, illustrating a key principle of gas behavior as described by Dalton's Law.
