Gas A (1 mol) dissociates in a closed rigid vessel of volume 0.16 litre as per following reaction : 3 A (g) rarr 2B (g) + 4C (g) If degree of dissociation of A is 0.2 and remain constant in entire range of temperature then correct P vs T graph is [Given : R = 0.08 atm L mol^(-1) K^(-1) ]

Answer»




Solution :`{:(3 A (g),rarr,2B (g),+,4C (g),),(1 MOL,,-,,,),(1 - 0.2,,0.2 xx (2)/(3),,0.2 xx (4)/(3),),(= 0.8,,,,,),(P = (n)/(V) RT,,,,,):}`
Total mole `= 0.8 + (0.4)/(3) + (0.7)/(3)`
`= (3.6)/(3) = 1.2`
`TAN THETA = m = (NR)/(V)`
`m = (1.2 xx 0.08)/(0.16) = 0.6`
