Density of carbon monoxide is maximum at

Options

A. `2 " atm" and 600K`
B. `0.5 " atm" and 273K`
C. `6 " atm" and 1092K`
D. `4 " atm" and 500K`

Answer

D

Explanation

From ideal gas equation , `d=(p M)/(RT)`
`because` M and R are constant for a particular gas `because d prop (p)/(T)` , i.e.,
(a) `(p)/(T)=(2)/(600)=0.0033`
(b) `(p)/(T)=(0.5)/(273)=0.00183`
(c) `(p)/(T)=(6)/(1092)=0.00549`
(d) `(p)/(T)=(4)/(500)=0.0080`
`because p //T` ration is highest at 4 atm and 500 K.
`therefore` Density of `CO` is maximumat this condition.
