a) Which curve (i, ii, iii, iv or v) corresponds to F2 → 2F- b) Which curve (i, ii, iii, iv or v) corresponds to Cl2 → 2C1- c) Which curve (i, ii, iii, iv or v) corresponds to Br2 → 2Br. d) Which curve (i, ii, iii, iv or v) corresponds to 12 → 21. e) Which curve (i, il, iii, iv or v) corresponds to CH3CH2-H f) The sign of H° for all of these steps is: Opositive Onegative -> Potential Energy Bond Dissocation Energy (BDE): the energy needed to break a bond homolytically (energy input: H>0, a positive energy value) the energy released in forming a bond (energy output: H 0, a negative energy value) → CH3CH2 + H. شکر Reaction coordinate iv
