second law of thermodynamics

Hello everyone
My problem is about second law of thermodynamics & reversible work.
according to carnot cycle equations we have q/q0=T/T0 which q is absorbed heat from hot reservoir & q0 is exhausted heat to cold reservoir.
but according to second law of thermodynamics we have
q0 =T0(Si-Se)+q(T0/TH)
1)what is difference between two equations for q0 ?
2) Are two terms T0(Si-Se) & q(T0/TH) Equivalent ?both are q0 .

I will check those your formulas later but i think the first is concern with carnot and Second law of thermodynamics. where it is Qh/Th + Qc/Qh = 0 remember it is a matter of impossibility. I will check your second formula and get a conclusion on it cos i dont really understand u from the second one

Aren't you confused with Exergy analysis?
