Using `S^(@)` values, calculate the entropy of the reaction,
`SO_(2)(g)+(1)/(2)O_(2)(g)toSO_(3)(g)`
The `S^(@)` values for `SO_(2),O_(2) and SO_(3)` are 248.5,205.0 and 256.2 J `K^(-1)" "mol^(-1)`.

Text Solution

Verified by Experts

The correct Answer is:
`-94.2JK^(-1)" "mol^(-1)`
`DeltaS_("reaction")^(@)=sumS_("products")^(@)-sumS_("reactants")^(@)`.
