QUESTION:
Calculate the pressure exerted by 1.0 mol C2H6 behaving as (a) a perfect gas, (b) a van der Waals gas when it is confined under the following conditions: (i) at 273.15 K in 22.414 dm3, (ii) at 1000 K in 100 cm3. Use the data in Table 1.6.
ANSWER:(a) (i) Pressure of perfect gas = nRT/V
= 1.0 mol × 8.314 J/K mol × 273.15 K/ 22.414 dm3
= 101.12 kPa
(ii) Pressure of perfect gas = nRT/V
= 1.0 mol × 8.314 J/K mol × 1000 K/ 0.1 m3
