Questions & Step-by-Step Solutions
Which of the following processes is spontaneous at constant temperature and pressure?
Step 1: Understand what a spontaneous process is. A spontaneous process is one that occurs naturally without needing to be driven by an external force.
Step 2: Learn about entropy. Entropy is a measure of disorder or randomness in a system.
Step 3: Know the conditions. The question specifies that the process is at constant temperature and pressure.
Step 4: Identify the key characteristic of spontaneous processes. At constant temperature and pressure, a spontaneous process is characterized by an increase in entropy.
Step 5: Conclude that if a process leads to an increase in entropy, it is likely to be spontaneous under the given conditions.
