dS = dQrev/T
Very important the analysis of this equation, since we can see that both entropy and heat are differential, therefore I imagine that T is temperature which can be a constant, therefore it becomes a differential equation that can be solved by integration.
The third law of thermodynamics is powerful and served humanity as a breakthrough to understand many industrial processes today where cooling and heat exchangers are involved.
Thanks for your valuable contribution friend, greetings.

Thank you for leaving this wonderful technical comment. From what I have studied the formula ds = dQᵣₑᵥ / T is the differential definition of entropy in classical thermodynamics. This mathematical expression connects the heat exchanged in a reversible way with the increase in disorder of the system. I hope I said it well because it seems to me that you know these topics better than me. I am someone who studied these things in the past, but it seems to me that you use these concepts daily in your work, is that right?
Yes, what happens when I see ds and dQ I realize that they are differential, being differential, it is most likely that the entropy is calculated with the heat integral, that is the technical mathematical aspect, but in the physicochemical aspect is as you very well explain it.
It is a pity that geographical barriers separate us, but I would have liked to meet you and share knowledge with you, my friend.
Greetings and blessings to you.
