Factors Affecting Vapour Pressure

Q. 3. N2O4 dissociates as N2O4 (g) - - - - >2NO2 (g) at 273 K and 2 atm pressure.The equilibrium mixture has a density of 41.What will be the degree of dissociation

Q. A liquid is transferred to a bigger vessel (with bigger surface area) at the same temperature. The vapour pressure of the liquid

1. increases
2. decreases
3. remains same

Q. The order of volatility of liquids A, B, C, D is A > C > B > D. The order of their vapour pressure is:

1. A
2. B
3. C
4. D

Q. Temperatures of liquids A, B, C, D are 25, 50, 75, 90 (${}^{0}C$) respectively. Order of their vapour pressures is:

1. A
2. B
3. C
4. D
