(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.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
