Enzymes accelerate reaction rates by 10 7 to 10 17 compared to the uncatalyzed reactions. The ratio of the rate of the catalyzed reaction to the rate of the uncatalyzed reaction ( rate cat / rate uncat ) is known as the rate enhancement. The rate enhancement can be related to the difference in the free energies of activation. Note: The difference in the free energies of activation, or Δ G ∘ ‡ uncat – Δ G ∘ ‡ cat , can be expressed more succinctly as Δ Δ G ∘ ‡ . Δ Δ G ∘ ‡ = R T ln ( rate cat rate uncat ) From the given rates, calculate the rate enhancement and the Δ Δ G ∘ ‡ in kilojoules per mole at T = 25 ∘ C . Enter each answer as a whole number. Uncatalyzed rate = 10 − 6 s − 1 Catalyzed rate = 10 2 s − 1 R = 8.3145 J / ( K ⋅ mol )

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
