The curve of pressure volume (PV) against pressure (P) of the gas at a particular temperature is as shown, according to the graph which of the following is/are incorrect (in low pressure region):

A

`H_(2)` and He shows +ve deviation from ideal gas equation.

B

`CO, CH_(4)` and `O_(2)` show negative deviation from ideal gas equation.

C

`H_(2)` and He show negative deviation while `CO, CH_(4)` and `O_(2)` show positive deviation.

D

`H_(2)` and He are less compressible than that of an ideal gas while `CO, CH_(4)` and `O_(2)` more compressible than that of ideal gas.

Text Solution

Sketch shows the plot of Z v/s P for a hypothetical gas for one mole at three distint temperature. Boyle's temperature is the temperature at which gas shows ideal behaviour over a pressure range in the low pressure region.Boyle's temperature (T_b)=a/(Rb) .If a plot is obtained at temperature 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 CO_2 and the temperature well above critical temperature curve is more like H_2 at 0^@C as shown above.At high pressure suppose all the constant temperature curve varies linearly with pressure according to the following equation : Z=1+(Pb)/(RT) ( R=2 cal "mol"^(-1) K^(-1) ) Which of the following is correct :
