Which of the following come under the view of thermodynamics?

Options

A. Predicting the feasibility of chemical change
B. Predicting the extent of completion of the chemical change
C. Rate at which chemical change occurs at a particular set of conditions
D. Effect of temperature on the rate of reaction

Answer

To determine which of the given options comes under the view of thermodynamics, we can analyze each option based on the principles of thermodynamics.

### Step-by-Step Solution:

1. **Understanding Thermodynamics**:
- Thermodynamics is the branch of chemistry that deals with the relationships between heat, work, temperature, and energy. It primarily focuses on the feasibility of chemical reactions and the energy changes associated with them.

2. **Analyzing the First Option**:
- **Predicting the feasibility of chemical change**:
- This option relates to the concept of Gibbs free energy (ΔG). According to thermodynamics, if ΔG < 0, the reaction is spontaneous; if ΔG = 0, the system is at equilibrium; and if ΔG > 0, the reaction is non-spontaneous.
- Therefore, this option falls under the view of thermodynamics.

3. **Analyzing the Second Option**:
- **Predicting the extent of completion of chemical change**:
- This involves understanding how far a reaction will proceed to completion, which is more related to kinetics and equilibrium rather than thermodynamics.
- Thus, this option does not come under the view of thermodynamics.

4. **Analyzing the Third Option**:
- **Rate at which chemical change occurs at particular set of conditions**:
- This option deals with the speed of the reaction, which is a concept of chemical kinetics. Thermodynamics does not provide information about the rate of reactions.
- Hence, this option does not fall under thermodynamics.

5. **Analyzing the Fourth Option**:
- **Effect of temperature on the rate of reaction**:
- Similar to the previous option, this also pertains to chemical kinetics. While thermodynamics can discuss how temperature affects the energy of a system, it does not directly address the rate of reaction.
- Therefore, this option is also not under the view of thermodynamics.

### Conclusion:
- The only option that comes under the view of thermodynamics is **predicting the feasibility of chemical change**.
