Given the following data for the reaction A -->B, determine the activation energy, Ea, of the reaction in J/mol. (3 sig figs)     k (1/s) T (K) 0.730 250 0.739 450

Question 6 of 25 Submit An experimental plot of In(k) vs. 1/T is obtained in lab for a reaction. The slope of the best-fit line for the graph is -4215 K. What is the value of the activation energy for the reaction in kJ/mol? kJ/mol 1 2 3 C 7 9. +/- x 10 0 LO 00

Which statement is incorrect for the following reaction profile?   A) The reaction is exothermic. B) The activation energy is 50 kJ/mol. C) ∆H = –25.0 kJ/mol. D) Point 2 is an activated complex. E) The products are lower in energy than the reactants.

For the interconversion between A and B as shown below, which of the following describes how the equilibrium constant (K) is related to the rate constants k1 and k -1 and to the amounts of A and B present at equilibrium? k1 A В k.1 OK = kj[A] and K = kj[B] k[B] K = kj[A] [B] K and K || [A] k1 [B] [A] K and K %3D k-1 k[A] K = kj[B]
