BCH 403 final exam questions 2023 Questions with Complete Solutions

Exam 1 Correct Answer- A reaction consists of a reactant "R" being converted into a product "P". The change in enthalpy of the conversion is 5 kJ/mol, while the change in entropy is 35 kJ/mol. Therefore, thermodynamic coupling is not required for this reaction to reach an equilibrium. True/False Correct Answer-True Which of the following is true regarding a reaction that has a ΔG° = 0. The concentrations of the reactants and products are equal. The reaction will eventually arrive at an equilibrium. The reaction will go forward quickly. The reaction will go forward slowly. The concentration of the product is unchanging. Correct Answer-The concentration of the product is unchanging. The enthalpy of water hydrogen bonding is the driving force behind the hydrophobic effect. True/False Correct Answer-False A solution of a weak acid (AH) with a pKa of 5.5 is adjusted to a pH of 7.5. According to the Henderson-Hasselbach equation, under these conditions the dissociated for
