The answer to the question is C
Answer : The partial pressure of
and
are, 84 torr and 778 torr respectively.
Explanation : Given,
Mass of
= 15.0 g
Mass of
= 22.6 g
Molar mass of
= 197.4 g/mole
Molar mass of
= 32 g/mole
First we have to calculate the moles of
and
.

and,

Now we have to calculate the mole fraction of
and
.

and,

Now we have to partial pressure of
and
.
According to the Raoult's law,

where,
= partial pressure of gas
= total pressure of gas
= mole fraction of gas


and,


Therefore, the partial pressure of
and
are, 84 torr and 778 torr respectively.
Answer:
Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.
Explanation:
The volume of a container is the space within the container. This is the amount of void the gas can occupy.
When the volume of a container is changed, the space either increases or decreases.
- An increase in volume creates more space within the container.
- This spreads out the force over a larger area.
When the volume of the container is reduced,
- the force is confined to much smaller space.
The frequency of collision is higher for tiny spaces.
But lower for a large volume.
