If P₁ partial pressure of a gas and x₁ is its mole fraction in a mixture, then correct relation between P₁ and x₁ is
Options
- AP _ total = P ₁ X ₁
- Bx ₁= P ₁ P _ total
- CP _ total =1- P ₁ x ₁
- DP _ total = P ₁ (1- x ₁ )
Correct answer
B. x ₁= P ₁ P _ total
Step-by-step solution
The correct relation between the partial pressure of a gas ( (P₁ ) ) and its mole fraction ( (x₁ ) ) in a mixture is given by Dalton's Law of Partial Pressures. According to this law, the partial pressure of a gas in a mixture is proportional to its mole fraction and the total pressure of the mixture. The expression can be written as: (P₁=x₁ P_ total ) From this relationship, we can derive the mole fraction as: (x₁= P₁ P_ total ) This corresponds to Option B: (x₁= P₁ P_ total )
