Solution

Dalton’s law of partial pressure:

  1. Statement: The total pressure of a mixture of two or more non-reactive gases is the sum of the partial pressures of the individual gases in the mixture.
  2. Explanation:
    Dalton’s law can be mathematically expressed as:
    PTotal = P1 + P2 + P3 …(at constant T and V)
    where, PTotal is the total pressure of the mixture and P1, P2, P3, … are the partial pressures of individual gases 1, 2, 3, … in the mixture.
    For example, consider two non-reactive gases A and B. On mixing the two gases, the pressure exerted by individual gas A in the mixture of both the gases is called partial pressure of gas A (say P1). Likewise, the partial pressure of gas B is P2. According to Dalton’s law, the total pressure of the mixture of gas A and B at constant T and V will be given as:
    PTotal = P1 + P2
