(C) molar bond energy (A) N-F (B) C-O (C) O-F (D) C-F. Answer. The energy which is required to break 1 mole of a given bond is called (A) energy required to make a mole of a compound (C) BF3 flashcard set, {{courseNav.course.topics.length}} chapters | The table below shows the bond energies relevant to this reaction: Energy In = 436 + 243 = 679 KJ / Mole, Energy Out = 2 x 432 = 864 KJ / Mole, Energy Change = 679 – 864 = -185 KJ / Mole, *The energy change is negative, showing that energy is released to the surroundings so is an exothermic reaction. View Homework Help - Bond Energy Worksheet Answers.pdf from CHEM 217 at Athabasca University, Calgary. You May Get A Slightly Different Result If You Use An Alternative SourceDo Not Include Units With Your Answer. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons In which of the following molecules, the bond lengths around the central atom are not equal? Example: An exothermic reaction. Chemistry Calculations; How to Calculate Bond Energy. Bond energy: The energy required to break a bond, Energy change = energy in – energy out. Hydrogen Bromide decomposes to form Hydrogen and Bromine: 2 x ( H – Br ) → H – H + Br – Br, Energy In = 2 x 366 = 732 KJ / Mole, Energy Out = 436 + 193 = 629 KJ / Mole, Energy Change = 732 – 629 = +103 KJ / Mole, *The energy change is positive, showing that energy is taken in from the surroundings so is an endothermic reaction.
