To solve the question regarding the total entropy change for a system and its surroundings, we need to analyze the relationship between the type of process (exothermic or endothermic) and the entropy changes involved. ### Step-by-Step Solution: 1. **Understanding Entropy Change**: - Entropy (S) is a measure of the disorder or randomness in a system. The total entropy change (ΔS_total) for a process is the sum of the entropy change of the system (ΔS_system) and the entropy change of the surroundings (ΔS_surroundings). - Mathematically, this can be expressed as: \[ ...
