Isothermal vs Reversible

Postby Harmony Becerra » Sun Feb 10, 2019 9:45 pm

Can someone explain the difference between isothermal and reversible systems? I understand that they require different equations but I do not know what the equations mean or when to use them.

Isothermal systems are reversible systems. They have a constant temperature and are less efficient with work. Irreversible reactions do not have a constant temperature (it decreases then increases in expansion) and use the W = -PV equation. Just remember that reversible and isothermal are basically synonyms here, and they both use the nRT ln (v1/v2) equation.

Actually reversible/isothermal systems are most efficient at doing work considering the area under the curve of reversible expansion vs irreversible expansion on Lavelle's outlines.
