The rate of a certain reaction is given by the following rate law: rate =k Use this information to answer the questions below. What is the reaction order in N,? What is the reaction order in H2? What is overall reaction order? At a certain concentration of N2 and H2, the initial rate of reaction is 0.820 M / s. What would the initial rate of the reaction be if the concentration of N2 were halved? Round M S your answer to 3 significant digits. The rațe of the reaction is measured to be 47.0 M/s when [N2] = 1.4 M and [H2] = 0.35 M. Calculate the value of the k = M rate constant. Round your answer to 2 significant digits.

The rate at which a certain drug is eliminated by the body follows first-order kinetics, with a half life of 69 minutes. Suppose in a particular patient the concentration of this drug in the bloodstream immediately after injection is 1.9 µg/mL. What will the concentration be 276 minutes later? Round your answer to 2 significant digits.

39. The decomposition of a certain pesticide was found to follow first-order kinetics. A student finds that after 3.0 months a sample of pesticide was 87.5% decomposed (only 12.5% of the pesticide remained). What is the half-life (112) for the decomposition reaction? a. 1.0 months b. 2.0 months 3.0 months d. The half-life can not be determined with the information provided.

In the nuclear industry, workers use a rule of thumb that the radioactivity from any sample will be harmless after 10 half-lives. What fraction of a radioactive sample remains after this time? (Radioactive decay obeys first-order kinetics.)
