MHT CET 2023 Chemistry question
Calculate for the following reaction at 300 K. NH_4NO_3(s) \rightarrow NH^+_{4(aq)} + NO^-_{3(aq)} ( = 28.1 kJ mol, = 108.7 J K mol)
Answer: (A)
Solution
, and for the surroundings at constant temperature and pressure . Here J K mol (the dissolution is endothermic, so the surroundings lose entropy).
