JEE Main levelSingle correct optionDifficulty 2 of 3ig132

Which of the following is the correct expression for the partial pressure of a component $i$ of an ideal gas mixture at temperature $T$ in volume $V$ ?

A $p_{i} = \frac{n _{i} RT}{V}$
B $p_{i} = \frac{n _{total} RT}{V}$
C $p_{i} = \frac{x _{i} RT}{V}$
D $p_{i} = \frac{n _{i} RT}{V _{i}}$

Answer: A

Each component behaves as if it alone occupied the whole volume

V

:

p_{i} = n_{i} RT / V

. Equivalently

p_{i} = x_{i} P_{total}

.
