When asked to write the second law of thermodynamics would we explain the delta S for reversible and irreversible processes? and for a reversible does it have to be isothermal reversible for delta Stotal to be 0 or can it simply be just reversible?

I don't think we have to do that. I think we can just say that entropy of the universe is greater than 0 for a spontaneous process and deltaS = q/t

Seconding the above answer. As long as you show your understanding that entropy is increasing in the universe I think it'll be fine.
