Answer:
The heat capacity of the bomb calorimeter is 7.58 J/°C.
Explanation:
First, we will calculate energy released on combustion:
= enthalpy change = -3267.5 kJ/mol
q = heat energy released
n = number of moles benzene=
q = -90.0657 kJ = -90,065.7 J
Now we calculate the heat gained by the calorimeter let it be Q.
Q = -q= -(-90,065.7 J) = 90,065.7 J (conservation of energy)
where,
Q = heat gained by calorimeter
c = specific heat capacity of calorimeter =?
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
The heat capacity of the bomb calorimeter is 7.58 J/°C.
