Questions & Step-by-Step Solutions
Which of the following processes is expected to have the largest positive change in entropy?
Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Identify the processes being compared. Look for processes that involve changes in the number of particles or states of matter.
Step 3: Consider the process of dissolving salt in water. When salt (solid) dissolves, it breaks into individual ions (particles).
Step 4: Recognize that the number of particles increases when salt dissolves. More particles mean more possible arrangements, which increases disorder.
Step 5: Compare this to other processes. If other processes do not increase the number of particles as much, they will have a smaller change in entropy.
Step 6: Conclude that dissolving salt in water is expected to have the largest positive change in entropy due to the significant increase in the number of particles.
