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 .
