An uncatalyzed reaction has a rate of 4.4 x 10-7 s–1 at room temperature (25 °C). When an enzyme is added the rate is 3.1 x 104 s–1. If the height of the activation barrier for the uncatalyzed rate is 28.6 kcal/mol, what is the height of the activation barrier for the catalyzed rate? Report your answer in terms of kcal/mol to the nearest tenths. Also, assume the pre-exponential terms for the uncatalyzed and catalyzed reactions are the same.

The activation energy of a certain reaction is 44.3 kJ/mol . At 30 ∘C , the rate constant is 0.0180s−1 . At what temperature in degrees Celsius would this reaction go twice as fast? Express your answer with the appropriate units. I'm so confused... When I worked this problem I got 317.67 K, or 44.67 C, but they're both wrong. What am I doing wrong?
Draw the major organic product(s) of the following reaction CH3 H3C-C-Cl NaOH + CH3 - You do not have to consider stereochemistry. If no reaction occurs, draw the organic starting material. When SN1 & El pathways compete, show both the substitution and the elimination products. Separate multiple products using the + sign from the drop-down menu. . Do not include counter-ions, e.g., Na+, I, in your answer
