3 gasses are mixed together (N2, O2, and He). The gauge of the N2 states a pressure of 1.23 atm. The gauge on the O2 tank shows 2.3 atm. The Helium gauge is broken. When the gasses are mixed, the total pressure of the tank is 6.50 atm. What is the pressure of the He? a) 3.47 atm
b) 2.97 atm
c) 0.435 atm
d) 10.03 atm

The pressure of the He is 2.97 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

Given : =total pressure of gases = 6.50 atm

= partial pressure of Nitrogen = 1.23 atm

= partial pressure of oxygen = 2.3 atm

= partial pressure of Helium = ?

putting in the values we get:

The pressure of the He is 2.97 atm

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

possibly, yes.
