The standard enthalpy change of solution for ammonium nitrate, NH4NO3 , is +25.7 kJ mol–1.
(a) Calculate the value for the standard entropy change in the surroundings, ∆Ssurroundings , when ammonium nitrate dissolves in water at 298 K.
Include a sign and units with your answer.
(b) Explain what can be deduced from your answer in (a) about the sign and the value of the standard entropy change in the system, ∆Ssystem , when NH4NO3 dissolves.
