a.) The rate constant for the base-catalyzed hydrolysis of ethyl acetate is 1.78×103 L mol-1 s -1 at 25 °C and 1.38×104 L mol-1 s -1 at 37 °C. Calculate EA, (delta)H‡ , the Arrhenius Constant, and (delta) S ‡ .

b.) The isomerization of HNC into HCN is important in the chemistry of interstellar gas clouds. HNC → HCN Has an activation energy of 210 kJ/mol and an activation entropy of -105 J mol-1 K-1 . Calculate the first-order rate constant at 30 K (temperature of a “hot” gas cloud).
