Energy Flow and Enzymes: Close Your System True or False

1. Which of the following has the greatest entropy? -> Leaves fallen from trees on the ground
2. Which of the following is not an example of an open system? -> A park
3. An endergonic reaction will only proceed spontaneously if -> the entropy of the system is increased.
4. The change in entropy of a system plus the change in entropy of the surroundings is -> always positive.
