Which statements below correctly explain how the entropy of surroundings of a reaction is related to the enthalpy of a reaction. Select all that apply. (a) The entropy of the surroundings equals the negative of the enthalpy of the reaction divided by the temperature. (b) As heat is gained or released in a reaction, the surroundings need to release or gain that heat. (c) When the surroundings release or gain heat, the entropy of the surroundings changes. (d) The enthalpy of a reaction is unrelated to the entropy of the surroundings.

Transcribed Image Text:**Entropy and Enthalpy in Chemical Reactions**
When considering the relationship between the entropy of the surroundings and the enthalpy of a chemical reaction, the following statements can be evaluated:
- **(a)** The entropy of the surroundings equals the negative of the enthalpy of the reaction divided by the temperature.
- **(b)** As heat is gained or released in a reaction, the surroundings need to release or gain that heat.
- **(c)** When the surroundings release or gain heat, the entropy of the surroundings changes.
- **(d)** The enthalpy of a reaction is unrelated to the entropy of the surroundings.
Understanding these options helps clarify the thermodynamic principles at play in chemical processes.
