Question

3) obtain the relationship between freezing point depression of a solution containing non Valatile non electrolyate and its molar mass. How much heat is evolved when 12g of co reacts with No2? The reaction is 4Co(g ) + 2 No(g) 4Co2(g) +N2(g)' ∆rH°
= -1200kJ.​

Answer 1

Answer:

Explanation:

The freezing point depression (ΔTf) is directly proportional to the molality of solution. ... Suppose we prepare a solution by dissolving W2 g of solute in W1 g of solvent. Moles of solute in W1 g of solvent = `"W"_2/"M"_2` where, M2 is the molar mass of solute
