Unformatted text preview: 1 1.) If the following statements are True, place a T in the line before the statement. If False, place an F. G = H T S is an equation that describes the second law of thermodynamics under constant T and P . In an ice/water mixture at 0C, G ice = G water . Entropy of water increases when you add a hydrophobic molecule. Increasing pressure on condensed matter always increases its Gibbs Energy. In a P vs T phase diagram a quadruple point (four phases existing simultaneously) can exist for a 2-component system. Water freezes spontaneously at -5C, therefore S sys is positive. 2. Refer to the following reaction coordinate diagram for the questions below. Place answers in box next to questions. Give answers in nearest kJ/mol. What is r G for A B What is the transition state energy for A B If this graph represented an uncatalyzed reaction, calculate the r G for an enzyme- catalyzed reaction of A B Free Energy (kJ/mol) Reaction Coordinate A B 10 20 30 40 2 For questions 3 - 5, circle the correct answer....
