### In the Figure, isotherms of CO2 at several temperatures near the critical point are shown. At the critical point (critical state), the distinction between the liquid and gaseous states disappear and the density of the gaseous substance is equal to that in the liquid state. For every gas this occurs at specific values of temperature and pressure, called critical temperature and critical pressure respectively. At temperatures and pressures above the critical point value, a gas is said be in a supercritical state. Critical constants are evaluated by solving the Vander W aals equation which is a cubic in volume. The values are Tc   In the supercritical region the behaviour is studied by plotting Z vs P plots. The variation in this region is studied with respect to boyles temperature a  At temperature  higher than CB the variation is linear (Plot I) and at temperature lower than CB the variation is non linear (Plot II) With reference to the passage answers the following questions: Q. Two vandaer waals gases have same value of 'a' but different value of b which of the following statement is correct.

QUESTION: 7

Sketch shows the plot of Z v/s P for of a hypothetical gas for one mole at three distinct temperature.  Boyle’s temperature is the temperature at which a gas shows ideal behaviour over a pressure range in the low pressure region. Boyle's temperature (Tb) = a/Rb . If a plot is obtained at temperatures well below Boyle's temperature then the curve will show negative deviation, in low pressure region and positive deviation in the high pressure region. Near critical temperature the curve is more likely as CO2 and the temperature well above critical temperature curve is more like H2 at 0°C as shown above. At high pressure suppose all the constant temperature curve varies linearly with pressure according to the following equation: Q.

Which of the following is correct:
