For the reaction A(s) rarr B(s) +C(s) ...

For the reaction
`A(s) rarr B(s) +C(s)`
Calculate the entropy change at `298K` and `1 atm` if absolute etropies (in `J K^(-1)mol^(-1))` are
`A = 130, B = 203, C = 152`

Text Solution

Verified by Experts

`DeltaS^(Theta) = sumS^(Theta) ("products") -sumS^(Theta) ("reactants")`
`=[S^(Theta)underset(B).+S^(Theta)underset(C ).] -[S^(Theta)underset(A).]`
`= [203 +152] - [130] = 255 JK^(-1)`
