Explanation
## Step 1: Definition of bond energyBond energy is the amount of energy necessary to disrupt a bond to generate separated atoms.## Step 2: Identifying relevant bond energy values from the given tableLooking at the reaction
, we see that this requires bond energies between Nitrogen (N-N), Hydrogen (H-H), and Nitrogen and Hydrogen (N-H). From the table provided, these bond energy values are 945 kJ/mol, 436 kJ/mol, and 391 kJ/mol respectively.## Step 3: Calculation of bond energies burnt and formed In the reaction, bond energy is used to break the N-N and H-H bonds in the reactants N2 and H2, while bond energy is released when the N-H bond forms in the product, NH3.The total energy used will be### **\( Used\:Energy=([N_{2}] * [940 kJ / mol]_{N_{2}}+(3* [436 kJ / mol]_{H_{2}})) \)**The total energy released will be ### **\( Released\:Energy=2 *3* ([391 kJ/mol]_{NH_{3}}) \)**Because for each NH3 molecule formed, three N-H bonds are formed.## Step 4: Calculation of the net energy change in the reactionTo calculate the net energy, we subtract the energy used from the energy released. Energy released will indeed be larger in this case because more and stronger bonds are formed in the pregnancy than the bonds that run. This results in the release of energy, making this spiral a heating process.#
