![### Entropy Calculations for a Chemical Reaction
#### Task
Calculate the entropy change of the surroundings (\( \Delta S_{\text{surr}} \)) and the universe (\( \Delta S_{\text{universe}} \)) for a given chemical reaction.
#### Reaction Details
**Consider the reaction:**
\[ \text{H}_2\text{S(g)} + 2\text{H}_2\text{O(l)} \rightarrow 3\text{H}_2\text{(g)} + \text{SO}_2\text{(g)} \]
**Where:**
\(\Delta S^\circ_{\text{rxn}} = 294.7 \, \text{J/K}\)
#### Instructions
Using standard thermodynamic data (found in the Chemistry References), calculate the entropy change of the surroundings and the universe at \(25^\circ \text{C}\).
#### Calculations Required
- \(\Delta S_{\text{surr}} = \) _____ J/K
- \(\Delta S_{\text{universe}} = \) _____ J/K
Students should refer to the Chemistry References for necessary data and perform calculations at standard temperature (\(25^\circ \text{C}\)).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F03536715-3e1d-4765-9555-fb0adbd33776%2Fcbd357cb-e963-4dd1-9b8c-77d2e7aca356%2Fv817k1_processed.jpeg&w=3840&q=75)
