Suppose the partial pressure of one gas in a mixture decreases by 5 kPa. How does this change affect the total prelssure of the mixture?

To understand how a decrease in the partial pressure of one gas affects the total pressure of the mixture, we need to consider Dalton's Law of Partial Pressures. According to this law, the total pressure exerted by a mixture of non-reacting gases is equal to the sum of the partial pressures of the individual gases.
In this case, if the partial pressure of one gas decreases by 5 kPa, it means that the pressure exerted by that particular gas reduces. However, the partial pressure of the other gases in the mixture remains unchanged.
So, to calculate the new total pressure of the mixture, we need to subtract the decrease in the partial pressure of the specific gas from the initial total pressure of the mixture.
Let's say the initial total pressure of the mixture is P_initial, and the partial pressure of the specific gas is P_partial. The new total pressure can be calculated using the following equation:
P_new = P_initial - P_partial
Therefore, the new total pressure of the mixture will decrease by the same amount as the decrease in the partial pressure of the specific gas.
