In my book it says that decreasing the atmospheric pressure increases the rate of evaporation. Can you please elaborate on this statement as I am not able to understand the concept behind this. Thank you

I can only guess at what your book is explaining as you haven't provided any context or background. However, evaporation of liquids occurs on the surface of the earth when energetic atoms from a liquid escape the body of the liquid and move into the atmosphere. Molecules of the gasses that are already present in the atmosphere will tend to get in the way of the evaporating atoms as they will collide with them. So if you reduce the pressure of the atmosphere and consequently reduce the number of molecules of gas present, there are fewer to get in the way. Result...? You tell me.
