The analgesic drug has a metabolic decomposition that follows 1st order kinetics, with a half-life of 150 minutes. The drug isadministered to a patient and the initial concentration of the drug is 0.00460 mol L-1. Calculate the concentration (in mol L-1)of the drug after 600 minutes.Give your answer to three significant figures using E notation (e.g. 3.25 x 105 could be entered as 3.25e-5, 3.25e-05, 3.25E-5or 3.25E-05) and without units.Answer:

The gas phase decomposition of dinitrogen pentoxide at 335 K N205(g)2 NO2(g) + ½ 02(g) is first order in N205. During one experiment it was found that when the initial concentration of N205 was 7.50×10-2 M, the concentration of N205 dropped to 2.09×10-2M after 198 s had passed. Based on this experiment, the rate constant for the reaction is || IS s-1.

The half-life of a reaction, t/2. is the time it takes for the reactant concentration A| to decrease by half. For example, after one half-life the concentration falls from the initial concentration [Alo to [Alo/2, after a second half-life to [A]o/4, after a third half-life to [Alo/8. and so on. on.
