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)` ]A. B. C. D. |

Answer» Correct Answer - D `{:(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` |
