`1`mol each of the following solutes are taken in `5`mol water, (a)`NaCl` (b)`K_(2)SO_(4)`( C)`Na(3)PO_(4)`(d) glucose Assuming `100%`ionisation of the electrolyte ,relative decrease in vapour pressure will be in orderA. NaClB. `K_(2)SO_(4)`C. `Na_(3)PO_(4)`D. glucose |

Answer» Correct Answer - C Relative decrease in vapour pressure `propto` mole fraction of solute. `{:("Solute","Mole in solution","Mole fraction of solute"),(A(NaCl)," "2," "(2)/(7)=0.29),(B(K_(2)SO_(4))," "3," "(3)/(8)=0.38),(C(N_(3)PO_(4))," "4," "(4)/(9)=0.44),(D("Glucose")," "1," "(1)/(6)=0.17):}` Hence, `DltAltBltC` |
