Compute the bond energy of the C-Cl bond using the reaction and data in question 10, the value of the bond energy for the C-H bond of 410 kJ/mol and the value of the H-H bond of 432 kJ/mol. The C-Cl bond energy in kJ/mol is:

The bond formation of C-Cl bond by applying the given data in  question 10 is 325.4 kJ

Explanation:

From the data in question 10:

The equation for the given reaction can be expressed as:

The enthalpy of formation of the compounds  are as follows:

Substance                      

                              - 74.8

                                  120.9

                          -95.8

From the data obtained above, the enthalpy of the reaction can be computed as follows:

However; since we knew to be  -262.8  kJ

At standard conditions

Bond     Bond Energy (kJ/mol)

C-H        410

H-H        432

The bond energy can be calculated by using the expression:

Thus; the bond formation of C-Cl bond by applying the given data in  question 10 is 325.4 kJ

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
