### Reversible and Irreversible

Can the second law be applied to irreversible reactions?

I think so, because entropy is a state function so the pathway does not matter

An irreversible reaction is one where the pressure remains constant. The second law of thermodynamics states that the entropy of the surroundings always increases. This would apply to irreversible reactions. However, entropy remains constant with reversible reactions because only infinitesimally small changes are happening.

yes entropy is a state function

Yes, since entropy is a state function, the second law can be applied to irreversible reactions.

yes the second law is applied to irreversible situations because entropy is a state function.
