![**Chemical Reaction Entropy Calculation**
Consider the reaction:
\[ 2\text{H}_2\text{O(l)} \rightarrow 2\text{H}_2\text{(g)} + \text{O}_2\text{(g)} \]
Using standard absolute entropies at 298K, calculate the entropy change for the system when 1.69 moles of \(\text{H}_2\text{O(l)}\) react at standard conditions.
\[ \Delta S^\circ_{\text{system}} = \underline{\hspace{3cm}} \text{ J/K} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3317a0bb-d2aa-43d5-b9a2-df6ae301c11d%2Fdfdf2b48-7701-43f3-961f-bf6e187cf587%2Ftw096po_processed.jpeg&w=3840&q=75)
