SUMMARY
The discussion centers on calculating the work of expansion in a chemical reaction occurring in a container with a cross-sectional area of 100 cm² and a piston that moves 10 cm against an external pressure of 101.3 kPa. The correct equation for this calculation is W = ∫ p dv, where the limits of integration should be defined as V1 and V2. Participants confirm the use of this equation to determine the work done by the system during the expansion process.
