To calculate the average atomic mass of carbon from this data: AAM = 0.989 (12) + 0.011 (13) = 12.01, which is the same as the number on the periodic table. Let's see what would happen if we changed the numbers. Let's say now the chemist finds that only 75% of the carbon in nature was carbon-12 and 25% was carbon-13.

Part c.ii Sample Response: Yes. Step 2 is slow; therefore, it is the rate-determining step of this mechanism. The rate law of this elementary reaction is rate = k [N₂O₄]. Because N₂O₄ is an intermediate, it cannot appear in the rate law of the overall reaction. Because Keq = [N₂O₄]/ [NO₂]² in step 1, [N₂O₄] = Keq [NO₂]².
