Reversible vs Irreversible

Postby Megan Purl 1E » Sun Feb 11, 2018 10:18 pm

How do the equations differ when calculating work for a system that is reversible vs a system that is irreversible?

They differ because you're taking the area under curve, and the area's are each different and have different equations. Lavelle has a detailed diagram on his website showing this. It's under the lecture outlines.

When it is reversible work, we use the equation W=-nRTln(v2/v1)
When it is irreversible work, W= -Pext (v2-v1)
