Time (s) [NO2] (mol/L) 0 0.500 1,200 0.444 3,000 0.381 4,500 0.340 9,000 0.250 (Note: The rate law only depends on the concentration of NO2.) Consider the reaction NO2(g) + CO(g) → NO(g) + CO2(g). The data in the table was obtained by observing the reaction. What is the order of this reaction? A. zero order B. first order C. second order D. third order

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

the correct answer to this question is 2
