Under what conditions will a pure sample of an ideal gas not only exhibit a pressure of `1 atm` but also a concentration of `1 mol litre^(-1)`
`[R= 0.082` iltre atm `mol^(-1)K^(-1)]`

Options

A. At STP
B. WhenV = 22.4litres
C. when T = 12K
D. Impossible under any conditions

Answer

C

Explanation

`PV = nRT`
`P = n/V RT because n/V = C rArr P = CRT`
`T = (P)/(CR) = (1)/(1 xx 0.0821) = 12K` .
