Balancing Atoms Organic chemistry reactions are often not written as balanced equations. This is because many organic chemists - who are just as lazy as anyone else - tend to be most interested in the organic product of a reaction. Side products are often ignored, and just as often catalysts and solution notation may be highly abbreviated or left out altogether. In addition, the reactions covered in Reactivity 1 and 2 were mostly simple 1:1 stoichiometry. However, let's look at balancing an organic reaction that you have seen. acetone H H 2-propanoxide The H- is really coming from LiAlH or NaBH4. How many acetone molecules could one LiAlH4 reduce? acetone +1 2-propanoxide + 1 1 A13+ LiAlH4 -> Li++

The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically written as k = Ae-E/RT where R is the gas constant (8.314 J/mol K), A is a constant called the frequency factor, and Da is the activation energy for the reaction. However, a more practical form of this equation IS In = (1-12) Ea R which is mathmatically equivalent to In Ea F (1/2 R T₂ k2 T1 where ki and k2 are the rate constants for a single reaction at two different absolute temperatures (T₁ and T₂). ▼ Part A The activation energy of a certain reaction is 42.1 kJ/mol. At 20 °C, the rate constant is 0.0150s¹. At what temperature in degrees Celsius would this reaction go twice as fast? Express your answer with the appropriate units. T₂ = Submit Part B Value k₂ = Request Answer Submit Given that the initial rate constant is 0.0150s¹ at an initial temperature of 20 °C, what would the rate constant be at a temperature of 200. °C for the same reaction described in Part…
