21 нояб. 2023 г. · The standard entropy change (ΔSsystemθ) for a given reaction can be calculated using the standard entropies (Sθ) of the reactants and products ...

... S∘(reactants) Δ S ∘ = ∑ ν S ∘ (products) − ∑ ν S ∘ (reactants). Here, ν ν represents stoichiometric coefficients in the balanced equation representing the ...

To calculate the entropy change for reactions, we simply look at the entropy of the final state minus the entropy of the initial state.

Subtract the total entropy of the products (what you end up with) from the total entropy of the reactants (what you started with). ∑Δ S (products) = S (CaO) + S ...

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.
