Entropy is a measure of disorder or randomness in a system, and processes that increase disorder typically have a positive change in entropy, while processes that decrease disorder have a negative change in entropy.
Let's analyze the given options:
1. **The deposition of carbon dioxide**: This process involves the transition from a gas (CO2) to a solid (dry ice), which generally results in a decrease in entropy because the gas phase has higher disorder than the solid phase. Therefore, this process is likely to have a negative change in entropy.
2. **A balanced reaction with a greater sum of coefficients on the right side of the reaction compared to the left side of the reaction**: If the products have a greater sum of coefficients than the reactants, this usually indicates an increase in the number of gas molecules, which can lead to an increase in entropy. Hence, this scenario is unlikely to have a negative change in entropy.
3. **A reaction that doubles the volume of the system**: Increasing the volume typically allows for greater molecular freedom and disorder, leading to a positive change in entropy.
4. **The denaturing of a protein**: Denaturing involves the unfolding of a protein's structure, which increases disorder, resulting in a positive change in entropy.
Based on this analysis, the option most likely to have a negative change in entropy is:
**The deposition of carbon dioxide.**
