Question: Define what is meant by unimolecular and bimolecular steps Why
Define what is meant by unimolecular and bimolecular steps. Why are termolecular steps infrequently seen in chemical reactions?
Answer to relevant QuestionsWhat two requirements must be met to call a mechanism plausible? Why say a “plausible” mechanism instead of the “correct” mechanism? Is it true that most reactions occur by a one- step mechanism? Explain. The reaction 2NO(g) + O2(g) → 2NO2(g) exhibits the rate law Rate = k[NO]2[O2] Which of the following mechanisms is consistent with this rate law? a. NO + O2 → NO2 + O Slow O + NO → NO2 Fast b. NO + O2 ⇌ NO3 Fast ...The following mechanism has been proposed to account for the rate law of the decomposition of ozone to O2(g): Apply the steady-state hypothesis to the concentration of atomic oxygen, and derive the rate law for the ...The decomposition of iodoethane in the gas phase proceeds according to the following equation: C2H5I(g) → C2H4(g) + HI(g) At 660. K, k = 7.2 × 10-4 s-1; at 720. K, k = 1.7 × 10-2 s-1. What is the rate constant for this ...A metallic solid with atoms in a face-centered cubic unit cell with an edge length of 392 pm has a density of 21.45 g/cm3. Calculate the atomic mass and the atomic radius of the metal. Identify the metal.
