The standard entropy change for a reaction is computed using standard entropies and:
AReaction rate constants
BMeasured bond lengths
CObserved colour changes
DStoichiometric coefficients
Answer & Solution
Correct answer: D. Stoichiometric coefficients
1. Entropy changes are summed over products and reactants.
2. The standard entropy change is written as a change in S with a degree symbol.
3. It may be computed using standard entropies.
4. In the expression, the Greek letter nu represents stoichiometric coefficients in the balanced equation.
