Constants I Periodic Table Part A For the following reaction studied in the gas phase (Fridgen, T. D., et al. J. Phys. Chem. A 2005, 109, 7519): Ci-+ C3H7CN → C1C3H7+ CN- Is the overall reaction exothermic or endothermic? Match the words in the left column to the appropriate blanks in the sentence on the right. the following potential energy surface was derived: [Cl–C;H;-CN]¯ Reset Help ClC;H,+ CN exothermic The overall reaction is because at a higher energy endothermic than the products are the reactants are Cl +C;H¬CN the transition state is [CIC;H,-CN] Submit Request Answer [Cl–C;H;CN] Reaction progress Part B The mechanism for the reaction, based on the potential energy diagram, There are six activation energies, one associated with each of the rate constants in the mechanism. Two of the elementary steps are barrierless, in that they have activation can be written as: energies equalling zero. Which of the six activation energies, Eal, Ea–1 Ea2 Ea-2 Ea3 Ea-3 are equal to zero? k…
