A proposed equation of state for a one component fluid is

=+ [1/]

0 2

where B0 and c are constants and the other symbols have their normal meanings.

Use this equation of state to obtain expressions for the following excess, molar quantities:

i)

ii)

iii) ,

iv)

v)

vi)

(3 marks) (3 marks) (1 mark) (1 mark) (3 marks) (1 mark)

b) An engineer wishes to use an equation of state to calculate ,, i.e. the molar heat capacity at constant pressure. They decide to use the formula

,=,+( )

Giving your reasons, state whether or not this equation is correct.
