Δ G INCREASES when Δ H INCREASES. This happens because the reaction needs more and more energy to occur (more endothermic), and therefore will not happen as spontaneously. What happens to Δ G when Δ H goes down ? WHY? Δ G DECREASES when Δ H DECREASES. This happens because the reaction needs less and less energy to occur (more exothermic), and therefore becomes more and more likely to happen spontaneously.

WHY? Δ G DECREASES when T INCREASES. AN INCREASE IN TEMPERATURE INCREASES KINETIC ENERGY OF MOLECULES MAKING IT MORE LIKELY THAT COLLISIONS AND REACTIONS WOULD TAKE PLACE. What happens to Δ G when T goes down ? WHY? Δ G INCREASES when T DECREASES. AN DECREASE IN TEMPERATURE DECREASES KINETIC ENERGY OF MOLECULES MAKING IT LESS LIKELY THAT COLLISIONS AND REACTIONS WOULD TAKE PLACE.

WHY? Δ G DECREASES AS Δ S INCREASES. AS DISORDER INCREASES (SINCE THAT IS THE NATURAL TENDANCY OF PROCESSES) SPONTANEITY WILL ALSO BECOME MORE LIKELY. What happens to Δ G when Δ S goes down ? WHY? Δ G INCREASES AS Δ S DECREASES. AS DISORDER DECREASES (SINCE THAT IS NOT THE NATURAL TENDANCY OF PROCESSES) SPONTANEITY WILL BECOME LESS LIKELY.

Why does decomposition of a dead animal happen in terms of energy? What would happen if we increase temperature? Why do we freeze food? Decomposition is the breakdown of ordered cells into disorder. It should happen naturally Δ G is negative . We freeze our food to LOWER TEMPERATURE, which also increases Δ G. This slows down decomposition. AT lower temperatures there is less kinetic energy, molecules move slower and therefore decomposition slows down. Explain the process of energy coupling. Give an example. Using exergonic (catabolic) reactions to fuel endergonic (anabolic) reactions. The breakdown of glucose (exergonic) to form ATP from ADP & P (endergonic). The breakdown of ATP (exergonic) to do cell work. What would be the overall change in free energy if an enzyme where to couple the energy released from ATP to the production of L-glutamine from L-glutamic acid and ammonia? Would the reaction be spontaneous? What does spontaneous mean? Δ G = -3.9 kcal/mol The reaction is spontaneous. Explain why plant cells need light energy to build sugar (in terms of energy). Building sugar is anabolic. Anabolic reactions are endergonic and thus require energy. An input of free energy is needed to generate order.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
