Reacting 1-chloro-2-ethylcyclohexene with hydrogen gas using a platinum catalyst would give a product of 1-chloro-2-ethylcyclohexane.
Hydrogen gas is a reducing agent, which in this reaction, simply mean that the alkene double bond in the cyclohexene will disappear because one of the two bonds forming the double bond (in the alkene) will be connected to a hydrogen atom. The platinum catalyst is necessary to allow the reaction to proceed at a much lower (activation) energy than would have been required.

Explanation:
1). The given data is as follows.
,
C = 5.73
Hence, calculate the change in enthalpy of the reaction as follows.
=
= -70.25 KJ
As, number of moles =
=
= 0.018 mol
Therefore, enthalpy of reaction in kJ/mol hexane is as follows.
= kJ/mol
Thus, we can conclude that for the reaction in kJ/mol hexane is
kJ/mol
.
2). As we know that,
Number of moles =
=
= 0.017 mol
=
= -65.875 kJ
As,
-65.875 kJ =
C = 4.56
Hence, heat capacity of the bomb calorimeter is 4.56 .
