The isomerization of cyclopropane follows first-order kinetics. The rate constant at 700 K is 6.20 x 10*(–4) min*(–1), and the half-life at 760 K is 29.0 min. Calculate the activation energy for this reaction. A) 5.07 kJ/mol D) 60. kJ/mol
B) 27.0 kJ/mol E) 270. kJ/mol
C) 50.7 kJ/mol

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
