How do you determine if a reaction is reversible or not? Does this information have to be given to you?

Usually, problems will state if they are reversible or irreversible. Some hints to know if they are reversible are when delta Stotal is equal to zero, making delta Ssystem=-delta Ssurroundings, and when temperature is constant, while volume increases and pressure decreases. Hope this helps!

I was in a UA review session and he said that usually the adiabatic (q=0) is irreversible--just another note!
