ALL sound waves are longitudinal, I know this of of many ways, I study astronomy and the sound waves of blackholes as they form. award me brainliest and I award you with a correct answer :)
The value of ΔS° for reaction is - 22.2 J/K.mol
→ 
Calculation,
Given value of S°(J/K.mol) for
= 248.5
= 240.5
= 210.6
= 256.2
Formula used:
ΔS° (Reaction) = ∑S°(Product) - ∑S°(Reactant)
ΔS° = (256.2 + 210.6 ) - ( 248.5 + 240.5) = 466.8 - 489 = - 22.2 J/K.mol
The change in stander entropy of reaction is - 22.2 J/K.mol. The negative sign indicates the that entropy of reaction is decreases when reactant converted into product.
