Transfer RNA can exist in two forms that are in rapid equi librium with each other; the equilibrium constant at 28 °C, K = [B]eq /[A]eq= 10. A temperature-jump experiment is done to measure the rates of interconversion. A solution of the tRNA at a concentration of 10 pM is quickly (faster than 10 ps) raised in temperature from 25 °C to 28 °C. An experimental signal is measured with a relaxation time τ = 3 ms. Assume that the mechanism is

a. What are the values of k and k_1 including units?

---

b. At what temperature are these values measured?

c. Would you expect doubling the concentration of tRNA to increase, decrease, or leave unchanged the values of τ, k1 and k_1?
