A) Sugar solution
B) NaCl solution
C) BaCl2 solution
D) Aqueous H2S
And reason behind the answer..

Answer 1

Which solution has highest effect of temperature on its vapour pressure ?

The relationship of temperature and vapor pressure is directly proportional which means that if temperature increases vapor pressure will also increase. The molecules of aqeous H2S tends to be more reactive at lower temperature than BaCl2 solution thus a change in temperature will most likely affect the vapor pressure of aqeous H2S.
