Question

Hh The first law of thermodynamics can be given as_ delta H degree rxn = 2) sigma n delta H degree f (products) - sigma m delta H degree f (reactants) deltaE = q + w delta S = qrev/T at constant temperature for any spontaneous process, the entropy of the universe increases the entropy of a pure crystalline substance at absolute zero is zero The thermodynamic quantity that expresses the extent of randomness in a system is_. internal energy enthalpy bond energy entropy heat flow the relationship between the entropy of a system and the num t Which one of the following correctly indicates the relationship between the entropy of a system and the num to f different arrangements, W, in the system? s=k/ws s=klnw s=w/k s=wk s=kw

Explanation / Answer

23) first law of thermodynamics is dE = q + w

24) Entorpy

entropy is measure of randomness and diaoreder of molenule present in amixure.

25) s = k ln W

25 S = -K Ln W
