WebIf the bond energy of a single P−P bond is 200 kJ mol¯ 1, what is the energy of the PP triple bond in P 2? Solution: Say you break all 6 P−P bonds in P 4, that is 6 x 200 = +1200. 1200 − 217 = 983 which is released when two P≡P bonds form. So 983 / 2 = bond energy of a P≡P bond. To three sig figs, the answer is 492 kJ/mol. eucerin itch relief moisturizing spray
