Entropy = q/t

So for the equation what does the "rev" mean? Is it reversible? and how does that affect the equation?

HI there, at constant pressure enthalpy equals q therefore, let's say you are trying to calculate the entropy of vaporization, you would just divide the enthalpy of vaporization by the temperature.

Yes, in the equation rev does mean reversible. This equation explains the change in entropy in terms of heat transfer (q) during a reversible process divided by the temperature(T) at which the process occurs.
