(a) Over what concentration range does the nickel component obey Henry's law?

(b) Determine the activity coefficient of iron at xN, = 0.5

(c) Check whether the Fe-Ni allov obeys regular solution theorv.

7.17 One mole of solid A at 1000 K is dissolved adiabatically in 3 moles of liquid B at 1200 K. The resulting solution obeys regular solution theory with an interaction energy of - 30 kJ/mole. Find:

(a) the final temperature of the solution

(b) the entropy change of the process

The melting temperature of A is 1100 K and its heat of fusion is 20 kJ/mole. The heat capacities of both liquid and solid A and of liquid B are all equal to 25 J/mole-K

where C is a constant.

7.16 The activities of Ni in the liquid Fe-Ni alloy at 1600°C are given below.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
