Question

Chapter 3: Bioenergetics and Enzymes 1. Define the First and Second Laws of Thermodynamics. 2. Identify/list the standard conditions Units of Measurement for standard free energy change Concentration pH 3. For the given G values below, characterize each as either exothermic or endothermic and whether or not the reaction would occur under spontaneous conditions. G (cal/mol) | Exothermic or Endothermic? Spontaneous? 8.2 5.5 4. Desc ribe the purpose/advantage of "coupling" endo- and exothermic reactions

Explanation / Answer

1. The first law, also known as LAW of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

2. T- 200C

P- 1atm

Conc- 1M

pH-

3. A. Exothermic Spontaneous

B. Endothermic Non- spontaneous

C. Endothermic Non- spontaneous

D. Exothermic Spontaneous

4. An exothermic reaction is coupled to an exothermic reaction so as to make the free energy change negative and total change in entropy positive.
