Question

Q.4) When solid N H 4 N o 3 is dissolved in water at 25 ° C , the temperature of the solution decreases. What is true about the signs of ∆ H and ∆ S for this process? (A) - ∆ H + ∆ S (B) - ∆ H - ∆ S (C) + ∆ H + ∆ S (D) + ∆ H - ∆ S

Answer 1

I think that that represents the solubility of the solution of NH4NO3 and water .here the solubility is been increased because temperature is inversely proportional to solubility
