## Reversible Processes

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### Reversible Processes

Hi I am still a bit confused on reversible processes and what they mean. I know that they are slow in process, but while measuring entropy in reversible processes if one factor was not constant, like when we calculate change in entropy of temperature, pressure, or volume, does that mean the remaining two things must be constant. Like if I tried to measure entropy change of a reversible change in temperature process, would that mean pressure and volume would have to be constant?

There can be more than one factor that isn't constant but then you'll have to combine other formulas like it would be a multi-step solution. A reversible process has the same entropy regardless if the reaction is favoring the reactants or products.
