Which of the following statements best compares geothermal energy and the energy from natural gas based on their rates of renewal? natural gas has a slower rate because any amount extracted is far lower than its generation inside earth. natural gas has a faster rate because, being a carbon resource, it quickly replenishes as part of the carbon cycle. geothermal energy has a faster rate because a vast amount of heat energy is always present inside earth's core. geothermal energy has a slower rate because the water present below earth's surface cools down periodically.

Achemist at a pharmaceutical company is measuring equilibrium constants for reactions in which drug candidate molecules bind to a protein involved in cancer. the drug molecules bind the protein in a 1: 1 ratio to form a drug-protein complex. the protein concentration in aqueous solution at 25 ˚c is 1.74 x10-6 m . drug a is introduced into the protein solution at an initial concentration of 2.00 x10-6m. drug b is introduced into a separate, identical protein solution at an initial concentration of 2.00 x10-6m. at equilibrium, the drug a-protein solution has an a-protein complex concentration of 1.00 x10-6m, and the drug b solution has a b-protein complex concentration of 1.40 x10-6m. a. calculate the kc value for the a-protein binding reaction. b. calculate the kc value for the b-protein binding reaction. c. assuming that the drug that binds more strongly will be more effective, which drug is the better choice for further research?
