## Reversible

$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### Reversible

In the notes, It says since a system is at equilibrium it is a reversible process? What does that mean? What is not a reversible process? What is the importance of it becoming a reversible process?

### Re: Reversible

Equilibrium by definition means something is reversible and happens in both directions. In terms of thermodynamics, we are talking about internal and external pressure being equal.

^^ What he said. If it's at equilibrium, it's reversible because it's done in infinitesimally small amounts.

### Re: Reversible

Equilibrium means that it is a dynamic equilibrium and a reaction is occurring in the forward and reverse directions. Therefore, if it is at equilibrium, it is reversible.

### Re: Reversible

By definition, at equilibrium forward and reverse reactions occur at the same rates. So, any reaction that is at equilibrium must be reversible.

### Re: Reversible

reversible means that even if there is an infinitesimal change in the system, there will be a significant change in the behavior of the system. the definitions of reversible in equilibrium reactions and thermodynamically, however, differ greatly.

### Re: Reversible

Why is the external pressure changing (slowly but still) in a reversible process?

### Re: Reversible

And what does effect does a common temperature have on the system doing work in a reversible process?
