If PD vs P (where P si pressure in atm and D is density in gm/lit). Is plotted for H_(2) ideal gas at a particular temperature. If [(d(PD))/(dP)]_(P = 8.21 "atm") = 10, then the temperature will be

Answer»

40 K
400 K
20 K
200 K

Solution : PD v/s P
`D = (PM)/(RT)`
`PD = (P^(2)M)/(RT)`
`(d (PD))/(DP) = (2PM)/(RT) = 10`
`(2 XX 8.21 xx 2)/(R xx T) = 10`
`T = (4 xx 8.21)/(0.0821 xx 10) = 40 K`
