Question 16

Dalton’s Law of Partial Pressure

Answer 16

The total pressure exerted by a mixture of two non-reactive gases is equal to the sum of the partial of the individual gases in the container.

Question 17

Graham’s Law of Diffusion

Answer 17

The rate of diffusion or effusion is inversely proportional to the root of molecular mass of the gas provided pressure, area and temperature are constant.
