I had a small doubt as follows:-
Given that (delta Tf) is the depression in freezing point of the solvent in a solution of non-volatile solute of molality m, the quantity
lim m-->0 (delta Tf/m) = ?
Please tell me the right ans. with explanation, I don't know the ans. It was asked in jee'94.
i suppose the ans. is Kf because as m tends to 0,i.e as the soln. becomes dilute it tends to behave more ideally.
yeah.. ann xavier is correct. I also got confused with the ques. when i saw it in an exam... actually, with m-->0, i-->1 and hence (delta TF/m)-->Kf
