A gas-forming reaction produces 1.10 m 3 1.10 m3 of gas against a constant pressure of 193.0 193.0 kPa. Calculate the work done by the gas in joules.

2.095 kJ.

Explanation:

Workdone by the gas is the pressure exerted in a unit volume of the container at constant temperature.

W = P * V

Where,

P = pressure in atm

101.325 kPa = 1 atm

193 kPa = 1/101.325 * 193

= 1.905 atm

V = volume in liters

1 m3 = 1000 l

1.10 m3 = 1100 l

W = 1100 * 1.905

= 2095.24 J

= 2.095 kJ.
