58.4 g of NaCl and 180 g of glucose were separately dissolved in l000mL of water. Identify the correct statement regarding the elevation of the boiling point (b.p) of the resulting solutions.

• NaCl solution will show higher elevation of boiling point

• Glucose solution will show higher elevation of boiling point

• Both the solutions will show equal elevation of boiling point

• The boiling point elevation will be shown by neither of the solutions

Which of the following will show a negative deviation from Raoult's law?

• Acetone-benzene

• Acetone-ethanol

• Benzene-methanol

• 0.5 g

• 1 g

• 0.75 g

• COCl₂

• CO₂, Cl₂

• None of these

Blood cells will remain as such in:

For an ideal solution, the correct option is :

• Δ_mix V ≠  0 at constant T and P

• Δ_mix H =  0 at constant T and P

• Δ_mix G =  0 at constant T and P

• Δ_mix S = 0 at constant T and P
