lower the activation energy in order to gain the thirty-fold increase in rate constant at 300K? (c) For the reaction C 2 H 5 I + OH - C 2 H 5 OH + I - k= 5.03 x 10 -2 M -1 s -1 at 289K and k= 6.71M -1 s -1 at 333K. What is the activation energy of the reaction? 4. (a) Consider a hypothetical reaction A + B P which is known (experimentally) to exhibit a third order rate law of the form -d[A] dt = k [A] 2 [B] show that the following mechanism is consistent with the rate law.

3 (this reaction mechanism is typically encountered in organic chemistry. Step 2 is a rearrangement.) (b) Give an expression for k obs in terms of k 1 , k -1 , k 2 , k -2 and k 3 . 5. It takes longer to cook food at high altitude because water boils at a lower temperature. At 8000 ft, water boils at 92° C rather than 100° C as at sea level. The chemical reaction involved in boiling eggs is the denaturation of a protein. If this reaction has an activation energy of 40kJ/ mole, how long would it take to cook an egg at 8000 ft to the same consistency as three-minutes of cooking at sea level? (i.e. how long does it take to cook a three-minute egg at 8000 ft?)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
