the value of Δ r S ∘ for the given reaction is to be identified from the given options. Concept introduction: In Spontaneous process, energy transfer from higher concentration to lower, or the energy is dispersed. Entropy (S) is the quantity to measure the dispersal of energy in the spontaneous processes. Δ r S ∘ is the change in entropy at standard condition and it is calculated by sum of the product of stoichiometric coefficients and molar entropies of products minus sum of the product of stoichiometric coefficients and molar entropies of reactants. That is, Δ r S ∘ = ∑ n S ∘ ( p r o d u c t s ) − ∑ n S ∘ ( r e a c tants)

Answer 1

Question

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.
