In a mixture of gases which do not react chemically together, the pressure of the individual gas is?
Answer Details
In a mixture of gases that do not react chemically together, the pressure of each individual gas is called its partial pressure.
When different gases are mixed together in a container, each gas behaves independently of the others. The total pressure exerted by the mixture of gases is equal to the sum of the partial pressures of each gas present in the mixture. This is known as Dalton's law of partial pressures. Mathematically, this can be represented as:
Total pressure = Partial pressure of gas A + Partial pressure of gas B + ... + Partial pressure of gas N
The partial pressure of each gas in the mixture depends on its mole fraction, which is the ratio of the number of moles of that gas to the total number of moles of all gases present in the mixture. The partial pressure of a gas can be calculated using the following formula:
Partial pressure of gas A = Mole fraction of gas A x Total pressure
Therefore, in a mixture of gases that do not react chemically together, the pressure of the individual gas is known as its partial pressure, and it can be calculated using the above formula.
