17 февр. 2024 г. · Delta S = q/t is used for isothermal reversible processes. Typically the q/T is used for phase changes. Delta S = nRlnV2/V2 is also used for isothermal ...

19 февр. 2022 г. · Yes, we can use the equation Delta S (system) = q (reversible run) / T. We can use delta H to find q. For instance, q = delta H(fusion) when melting ice.

9 февр. 2019 г. · delta S = nCpln(T2/T1) for constant pressure and delta S = nCvln(T2/T1) for constant volume. For the values of the heat capactities, ...

23 янв. 2016 г. · Delta S=(nRT*ln(V2/V1))/T. T then cancels and you are left with Delta S= nR*ln(V2/V1). I hope that helped!

13 февр. 2020 г. · delta S is the total between delta S of the surroundings and the system. ... Using the formula deltaG=deltaH - TdeltaH you can see if a reaction ...

28 февр. 2022 г. · A positive delta S doesn't reveal the spontaneity of a reaction. If you consider it with the formula delta G = delta H - T*delta S, it can ...

12 мар. 2022 г. · The book gives this equation: delta S (surr)=-deltaH/T. Here when theey mention delta h they are mentioning delta h of the system and not the ...

Delta S total is the sum of delta S of the surroundings and delta S of the system; it must be positive in order to have spontaneity.

dS= q/T is only used for isothermal processes, where T stays constant. If we look at the surroundings, it is usually such a large reservoir that any heat added ...

15 февр. 2018 г. · S is the entropy of a substance while delta S is the change in entropy. We use S to calculate delta S of a reaction (entropy of products - entropy of reactants ...
