Question

write the expression for relative lowering of vapour pressure​

Answer 1

ᴀɴsᴡᴇʀ-:

Let us assume that p is the vapour pressure of the solvent and ps is the vapour pressure of the solution, then the lowering of vapour pressure can be written as (p – ps). This lowering of vapour pressure relative to the vapour pressure of the pure solvent is called the Relative lowering of Vapour pressure.
