To calculate the total energy required when old bonds are broken, we need to know the specific chemical reaction taking place. Since the reaction is not provided, we will assume a common addition reaction involving an alkene and hydrogen iodide (HI), as the bond energies for C=C, H-I, and C-I are given in the table. Let's assume the reaction is the addition of hydrogen iodide to an alkene, for example: CH_2=CH_2 + HI → CH_3CH_2I In this reaction, the "old bonds" that are broken are one C=C bond and one H-I bond. Step 1: Identify the bonds to be broken. Based on the assumed reaction, the bonds broken are: • One C=C bond • One H-I bond Step 2: Retrieve the bond energy values from the provided table. • Energy of C=C bond = 614 kJ/mol • Energy of H-I bond = 299 kJ/mol Step 3: Calculate the total energy required to break these bonds. The total energy required to break the old bonds is the sum of the energies of the C=C bond and the H-I bond. Total energy required = Energy(C=C) + Energy(H-I) Total energy required = 614 kJ/mol + 299 kJ/mol Total energy required = 913 kJ/mol The total energy required when the old bonds are broken is 913 kJ/mol.
