### Determining if reversible or irreversible

How do we determine if a reaction is reversible or irreversible, or will all related questions explicitly state it?

### Re: Determining if reversible or irreversible

One way to determine whether a reaction is reversible or irreversible is to look at the delta S. If delta S is equal to zero, the reaction is reversible (this is an ideal process). If delta S is greater than zero (all real processes), then the reaction is irreversible because heat/energy is lost to the surroundings. I'm pretty sure you may or may not be given this information depending on what other information is given in the question.

I'm pretty sure you have to be told whether it is reversible or irreversible, just make sure to know which equations to know for what kind of reaction.
