Unformatted text preview: temperature and identify its location should it exist, (b) the regions where product A is formed in preference to B , and where the reverse is true. (c) Is the difference in the enthalpies of activation positive or negative? What about the differences in entropies of activation positive or negative? Provide a reason for your responses. (d) Which product, A or B , is kinetically preferred based solely upon the differences in entropies of activation? Explain. (e) Which is kinetically preferred based solely upon the differences in enthalpies of activation? Explain. (f) Is the prediction based upon enthalpic considerations in agreement or opposite to the prediction based upon entropic considerations alone? 1/T ln(A/B) 5. Write, by inspection, an expression for the rate of formation of B , assuming that a steady state analysis can be performed on the intermediate, I . The symbols R and C refer to reagents. A + R k 1 k 2 I C k 3 B...
