ANSWER:Solution:
Here we have to find out among the given reaction which have larger So value and have to explain ΔSo value be positive or negative.
The given reactions are
Step 1
(a)
The increase in ΔSo value depends on the number of mole of product formed from the reactant. If number of mole of product is greater than that of the number of mole of reactant than the entropy increases similarly if the number of moles decreases from reactant to product, then the entropy decreases.
Here in the reaction “B” the number of product formed is higher than that of the number of moles of reactant involved in the reaction.
Thus the change in entropy (ΔSo) of reaction “B” is higher.
