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 arriv...
