The overall order of an elementary step directly corresponds to its molecularity. Both steps in this example are second order because they are each bimolecular. Furthermore, the rate law can be determined directly from the number of each type of molecule in an elementary step. For example, the rate law for step 1 is
rate=k[NO]^2
The exponent "2" is used because the reaction involves twoNO^2 molecules. The rate law for step 2 is
rate=k[N_2O_4]^1[CO]^1=k[N_2O_4][CO ]
because the reaction involves only one molecule of each reactant the exponents are ommitted.
Analyzing a new reaction Consider the following elementary steps that make up the mechanism of a certain reaction: 1.3A>B+C 2. B+2D>C+F
A. What is the overall reaction? Express your answer as a chemical equation.
B. Which species is a reaction intermediate?
C. What is the rate law for step 1 of this reaction? Express your answer in standard MasteringChemistry notation. For example, if the rate law is type k*[A]*[C]^3.
D. What is the rate law for step 2 of this reaction? Express your answer in standard MasteringChemistry notation. For example, if the rate law is type k*[A]*[C]^3.

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol
