### Exercise 18.46 - Enhanced - with Feedback

#### Topic: Thermodynamics

Consider the following reaction:

\[ 2\text{Ca}(s) + \text{O}_2(g) \rightarrow 2\text{CaO}(s) \]

- \( \Delta H_{\text{rxn}} = -1269.8 \, \text{kJ} \)
- \( \Delta S_{\text{rxn}} = -364.6 \, \text{J/K} \)

Assume that all reactants and products are in their standard states.

*You may want to reference (Page) Section 18.6 while completing this problem.*
