(i) Does isopentane behave like an ideal gas? Justify your answer.

(ii) Given that a = 17.0 L^2.atm/mol2 and b = 0.136L/mol calculate the pressure of
isopentane as predicted by the van der waals equation.

(b) The elements of group 5A, the nitrogen family, form compounds with hydrogen
having the boiling points listed below:

SbH3 -17ºC; AsH3 -55ºC; PH3 -87ºC; NH3 -33ºC
