Calculate Work of Expansion in Chemical Reaction | 100 cm2 Container

Click For Summary
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.

PREREQUISITES
  • Understanding of thermodynamic principles related to work and pressure.
  • Familiarity with calculus, specifically integration techniques.
  • Knowledge of the ideal gas law and its applications.
  • Basic concepts of chemical reactions and their effects on gas behavior.
NEXT STEPS
  • Study the derivation and applications of the work equation W = ∫ p dv.
  • Learn about the ideal gas law and its implications for work calculations.
  • Explore examples of work done in various chemical reactions.
  • Investigate the effects of external pressure on gas expansion in closed systems.
USEFUL FOR

Chemistry students, chemical engineers, and anyone involved in thermodynamics or physical chemistry who needs to calculate work done in gas expansion scenarios.

Homework Statement



A chemical reaction takes place in a container of cross-sectional area 100 cm2. The container has a loosely fitting piston at one end. As a result of the reaction, then piston is pushed out by 10 cm against an external pressure of 101.3 kPa. Calculate the work of expansion done by the system.

I really don't know what equation to be using?
 
Physics news on Phys.org
is it

W = \int^v_v p dv
 
Yes, that's the one. Except the limits should probably be "V1" and "V2".
