## Reversible vs. Irreversible

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

### Reversible vs. Irreversible

How can you tell if a reaction is irreversible or reversible?

You have to be given certain information about a reaction to formulate and calculate things about a reaction, and one information is whether or not a reaction is reversible or not. Forgive me if I’m wrong, but I think a problem will typically tell you whether or not a reaction is reversible or irreversible.

### Re: Reversible vs. Irreversible

Almost all real world reactions that occur are irreversible, since the change in volume happens spontaneously. A reversible reaction is purely hypothetical, since it cannot happen in the real world. However, in the case of this class, the problem will probably tell you if they want you to calculate for a reversible or irreversible pathway.
