Question 3.
At 298 K, the molar ratio of NH3 and H2O is 1: 8.5 in an ammonia-water solution,
which we called A and the vapor pressure of NH3 is 10.64 kPa on the solution. For
another ammonia solution B, the molar ratio of NH3 and H20 is 1:21 and the pressure
of NH3 is 3.597 kPa. Calculate:
(1) AG when we transfer 1 mol NH3 (g) from a huge amount of solution A into a huge
amount solution B.
(2) AG when we dissolve 1 mol NH3 (g) into a huge amount of solution B at 1 bar.
