The van der Waal's equation of state for 1 mole real gas is `(P + (a)/(V^(2))) (v - b) = RT`....(i)
The Virial equation for 1 mole real gas is `PV = RT [1 + (x)/(V) + (y)/(V^(2)) + (z)/(V^(3))+....." To higher power of " V]` ....(ii)
when x, y and z are constants which are known as 2nd, 3rd adn 4th co-efficients respectively. The temperature at which real gas obeys ideal gas equation i.e., `(PV = nRT)` is known as Boyle's temperature.
Answer the following questions on the basis of the above write up :
If equation (ii) can be one of the way of writing of equation (i), then what will be the value of y?
