Theophylline is a phamaceutical drug that is sometimes used to help with lung function. You observe a case where the initial lab results indicate that the concentration of theophylline in a patient’s body decreased from 2.0 × 10-3 M to 1.0 × 10-3 M in 24 hours. In another 12 hours, the drug concentration was found to be 5.0 × 10-4 M. What is the value of the rate constant for the metabolism of this drug in the body?
Answer to relevant QuestionsConsider the hypothetical reaction A + B + 2C → 2D + 3E where the rate law is An experiment is carried out where [A]0 = 1.0 × 10-2 M, [B]0 = 3.0 M, and [C]0 = 2.0 M. The reaction is started, and after 8.0 seconds, the ...Write the rate laws for the following elementary reactions. a. CH3NC(g) → CH3CN(g) b. O3(g) + NO(g) → O2(g) + NO2(g) c. O3(g) → O2(g) + O(g) d. O3(g) + O(g) → 2O2(g) e. 614C → 714N + β particle (nuclear decay) The rate law for the reaction BrO3-(aq) + 3SO32-(aq) → Br2(aq) + 3SO4 2-(aq) is Rate = k[BrO3-][SO32-][H+] The first step in a proposed mechanism is The second step is rate determining.
