6- The reaction (CH;);CBr + OH→ (CH3);COH + Br in a certain solvent is first order with respect to (CH3);CBr and zero order with respect to OH. In several experiments, the rate constant k was determined at different temperatures. A plot of In(k) versus 1/T was constructed resulting in a straight line with a slope value of -1.10 × 10ʻ K and y- intercept of 33.5. Assume k has units of s'. a. Determine the activation energy for this reaction. b. Determine the value of the frequency factor A. c. Calculate the value of k at 25°C.

Im still confused on where you got 3.58, could you please expand upon that?

You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C₃₄H₃₂FeN₄O₄, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 34.9 micrograms of Fe. What is the mass percent of hemoglobin in your protein sample?   -don't prematureley round
