When a solute spontaneously dissolves in a liquid, the process is often exothermic. NH,NO3, however, spontaneously dissolves in water endothermically and is thus used in cold packs. Which is TRUE about the dissolution of NHẠNO3? Select one: O a. The AH of the process is zero. O b. The increase in entropy during dissolution outweighs the positive change in enthalpy. The AS of the process is negative. O d. The AG of the process is positive.
