Berthelot proposed the following empirical relation to explain the real behaviour of the real gases :

P+aTV2(V-b)=RT

If the Berthelot equation of state be one of the forms of virial equation for 1 mole real gas is as under:

PV=RT1+AV+BV2+CV3+. to higher powe rof n

where A, B and C are constants which are known as second, third and fourth virial coefficients respectively. Then what will be the correct value of Boyle's temperature i.e., TB i.e., the temperature at which PV=RT i.e., ideal gas equation is obeyed?
