Consider a reaction in which H = -20. kJ/mol and S = 10. J/mol · K. a. Calculate the G for this reaction at 25°C. b. Is the reaction spontaneous (explain your answe r)? Answer: a. G = H − TS  G = –20,000 J/mol – (298 × 10 J/mol) = −23,000 J/mol b. The reaction is spontaneous because the G is negative. Difficulty: Moderate Section 1.1 Learning objective: Apply the basic principles of t hermodynamics, equilibrium, and kinetics to biologi cal systems. MULTIPLE CHOICE 16.
