A gas‑forming reaction produces 1.85 m 3 1.85 m3 of gas against a constant pressure of 119.0 kPa. 119.0 kPa. Calculate the work done by the gas in joules. Hint: be sure to convert the cubic meters to liters and kilopascals to atm. Look up the conversion factors!

Answer:

[tex]W=220.15kJ[/tex]

Explanation:

Hello,

In this case, the work in terms of volume and constant pressure is:

[tex]W=p\Delta V[/tex]

In such a way, since at the beginning there is no gas due to the fact that it is a gas-forming reaction, the work results:

[tex]W=pV_2=119.0kPa*1.85m^3=220.15kJ[/tex]

So no need of units conversion is present since kPa and cubic meters yields kJ.

Best regards.
