Question

0.950 M-15-1 at 508'T. a. Calculate the activation energy and Arrhenius preexponential factor for this reaction. b. What is the value of the rate constant at 400°C? P29 The melting of double-strand DNA into two single strands can be initiated using temperature-jump methods. Derive the expression for the T-jump relaxation time for the following equilibrium involving double-strand (DS) and single-strand (SS) DNA: DS > 25 Skr P30 Consider the reaction
