Final answer:
Entropy tends to be directly proportional to molecular complexity because more complex molecules have a greater number of possible configurations, leading to higher disorder or randomness.
Step-by-step explanation:
The relationship between molecular complexity and entropy (ΔS) is typically directly proportional. In other words, as molecules become more complex, having more parts and a higher degree of freedom for movement and arrangement, the entropy usually increases. The increased number of possible configurations for a complex molecule results in higher disorder or randomness, which is associated with higher entropy. However, it is also essential to take into account other factors such as temperature and pressure when considering changes in entropy.
