Problem 85E

Catalysis (Section)

The enzyme carbonic anhydrase catalyzes the reaction CO2(g) + H2O(I)→HCO3 - (aq) + H+ (aq). In water, without the enzyme, the reaction proceeds with a rate constant of 0.039 s-1 at 25 °C. In the presence of the enzyme in water, the reaction proceeds with a rate constant of 1.0 x 106 s-1 at 25 °C. Assuming the collision factor is the same for both situations, calculate the difference in activation energies for the uncatalyzed versus enzyme-catalyzed reaction.

CHEM 123 Dr. Eric Taylor Class Notes –Week of 9/11­9/15 Monday 9/11 Chapter 5: Compounds and Bonding An octet tries to be accomplished by representative electrons.  Exception: H & He only require a duet Bonds  Ionic losing/gaining – transfer of electrons; metals reacting with nonmetals  Covalent nonmetals bonding/ sharing Ionic charge from Group #s  Metals form positive ions  Group # indicates how many electrons will be lost  To find charge of a positive ion = to group #  To find charge of a negative ion = subtracting 8 or 18 from group #  Be familiar with chart on slide 6­ typical ionic charges Ions  Ions achieve the electron configuration of their nearest noble gas (outer most valence shell)  METALS in Groups 1A
