PV versus T graph of equal masses of `H_2,He and O_2` is shown in fig. Choose the correct altermative

Options

A. C corresponds to `H_2,B` to `He and A` to `O_2`
B. A corresponds to He, B to `H_2 and C` to `O_2`
C. A corresponds to He, B to `O_2 and C` to `H_2`
D. A corresponds to `O_2,B` to H_2 and C` to He

Answer

A

Explanation

`PV=m/MRTrArr(PV)/T prop1/M`
`((PV)/T)_Alt((PV)/T)_Blt((PV)/T)_C`
`rArrM_AgtM_BgtM_C`
