The enthalpy of combustion of benzoic acid (c6h5cooh) which is often used to calibrate calorimeters, is −3227 kj/mol. when 1.09 g of benzoic acid was burned in a calorimeter, the temperature increased by 3.662◦c. what is the overall heat capacity of the calorimeter? the overall heat capacity includes the calorimeter hardware and the water that is in it. answer in units of kj/ ◦c.

Answer : The heat capacity of the bomb calorimeter

Explanation :

First we have to calculate the heat released by the combustion.

where,

q = heat released by combustion = ?

n = moles of benzoic acid =

= enthalpy of combustion = 3227 kJ/mole

Now put all the given values in the above formula, get:

Now we have to calculate the heat capacity of the bomb calorimeter.

Heat released by the reaction = Heat absorbed by the calorimeter

where,

q = heat released by the reaction  = 28.8 kJ = 28800 J

= heat capacity of calorimeter = ?

= change in temperature =

Now put all the given values in the above formula, we get:

Therefore, the heat capacity of the bomb calorimeter
