Final answer:

To calculate the work done by a chemical reaction, use the formula Work = Pressure * Change in Volume. Substitute the given values into the formula to find the work done in joules.

Step-by-step explanation:

To calculate the work done by a chemical reaction, you can use the formula:
Work = Pressure * Change in Volume

Given that the initial volume (V1) is 3.1 L, the final volume (V2) is 3.4 L, and the external pressure (P) is 3.9 atm, we can substitute these values into the formula to find the work:

Work = 3.9 atm * (3.4 L - 3.1 L)

Solving this equation will give you the work done in joules.
