Chapter 7.3, Problem 1C
Summary Introduction

To determine: Whether ∆G is zero, or have a positive value or a negative value in a reaction in which enthalpy decreases and entropy increases.

Introduction: Under conditions of a biochemical reaction, free energy (G) is defined as the amount of energy available to perform work. Entropy is defined as degree of randomness in a system and enthalpy is defined as the total potential energy of a system.

Summary Introduction

To determine: Whether the given reaction in which enthalpy decreases and entropy increases is endergonic or exergonic.

Introduction: The chemical reactions are of two types, namely exergonic reaction and endergonic reaction. The type of reaction in which energy is released to the surrounding is known as exergonic reaction. This type of reactions is a spontaneous reaction and the Gibbs free energy (∆G) value for this reaction is negative. The type of reaction in which energy is absorbed from the surrounding is known as endergonic reaction. This type of reaction is a non-spontaneous reaction and the ∆G value for this reaction is positive.

For a particular reaction, AH° = −16.1 kJ/mol and AS° = −21.8 J/(mol·K). Assuming these values change very little with temperature, at what temperature does the reaction change from nonspontaneous to spontaneous in the forward direction? OT= Is the reaction in the forward direction spontaneous at temperatures greater than or less than the calculated temperature? less than greater than K
Which of the following statements are true for BOTH the "transition state" and an "intermediate" of reaction? (This is a multi-select question, select all that apply.). Both are only observed in enzyme-catalyzed reactions. Both can be converted to product(s) or might decompose back to the reactant(s). Neither are part of the "net equation" for the reaction. Both contain covalent bonds are in the process of breaking and/or forming. Both are part of every chemical reaction. (i.e. the mechanisms of all chemical reactions, whether enzyme catalyzed or not, will have involve both a transition state and an intermediate).
For this reaction: 6CO2 + 6H2O → C6H12O6 + 6O2, the products have 2760 kJ/mole more free energy than the reactants. So, which of the following statements best describes the reaction? a The reaction is endergonic because it converts molecules with less free energy to those with more free energy. b The reaction is exergonic because it converts molecules with less free energy to those with more free energy. c The reaction is exergonic because it converts molecules with more free energy to those with less free energy d The reaction is endergonic because it converts molecules with more free energy to those with less free energy.
