Question 27 POST_UTME_UNIOSUN • 2025 • PHYSICS • objective

A container of volume $V$ contains a mixture of ideal gases with molar \fractions $x_1$, $x_2$, and $x_3$. If the temperature of the mixture is $T$ and the pressure is $P$, what is the partial pressure $P_1$ of the first gas?

Answer Options

Correct Answer A. The partial pressure $P_1$ is equal to the total pressure $P$ times the molar \fraction $x_1$.
B. The partial pressure $P_1$ is equal to the total pressure $P$ divided by the molar \fraction $x_1$.
C. The partial pressure $P_1$ is equal to the total pressure $P$ minus the molar \fraction $x_1$.
D. The partial pressure $P_1$ is equal to the total pressure $P$ plus the molar \fraction $x_1$.
Correct Answer
A
Correct Option:
The partial pressure $P_1$ is equal to the total pressure $P$ times the molar \fraction $x_1$.
