Q
Q: Which of the following processes has a positive ΔG?
Solution:
Photosynthesis is an endothermic process that requires energy, resulting in a positive ΔG.
Steps: 5
Show Steps
Step 1: Understand what ΔG means. ΔG represents the change in free energy during a process.
Step 2: Know that a positive ΔG means the process requires energy to occur.
Step 3: Identify the process in question. In this case, it is photosynthesis.
Step 4: Recognize that photosynthesis takes in energy from sunlight to convert carbon dioxide and water into glucose and oxygen.
Step 5: Conclude that since photosynthesis requires energy, it has a positive ΔG.
