MCQ
The total pressure of a mixture of two gases is equal to :
- ✓Sum of their partial pressures
- BThe difference in partial pressures
- CThe product of partial pressures
- DNone of these
✓
Answer
Correct option: A.
Sum of their partial pressures
The total pressure of a mixture of two gases is equal to sum of their partial pressures.
Let $\ce{P_A}$ and $\ce{P_B}$ be the partial pressures of two gases $A$ and $B$ and $\ce{P_T}$ be the total pressure of the gaseous mixture.
Then ${P_T=P_A+P_B}$
Let $\ce{P_A}$ and $\ce{P_B}$ be the partial pressures of two gases $A$ and $B$ and $\ce{P_T}$ be the total pressure of the gaseous mixture.
Then ${P_T=P_A+P_B}$
