The correct Answer is:
To solve the question regarding the formation of micelles, we will follow these steps: ### Step-by-Step Solution: 1. **Understanding Micelles**: Micelles are aggregates of surfactant molecules that form in solution. They are important in surface chemistry and colloidal systems. 2. **Concentration and Temperature**: The formation of micelles occurs when the concentration of surfactants in a solution exceeds a certain threshold. This is because, at lower concentrations, surfactant molecules remain as individual entities rather than aggregating into micelles. 3. **Critical Micelle Concentration (CMC)**: The concentration at which micelles begin to form is known as the Critical Micelle Concentration (CMC). It is essential to note that micelles will not form below this concentration. 4. **Temperature Influence**: In addition to concentration, temperature plays a crucial role in micelle formation. There is a specific temperature known as the "kraft temperature" (or "Kraft point") above which micelles can form. 5. **Conclusion**: Therefore, the formation of micelles takes place only above the Kraft temperature. This means that if the temperature is below this point, micelles will not form regardless of the concentration of surfactants. ### Final Answer: The formation of micelles takes place only above the Kraft temperature. ---
