Sodium carbonate (na2co3) reacts with acetic acid (ch3cooh) to form sodium acetate (nach3coo), carbon dioxide (co2), and water (h2o). a chemist carries out this reaction in a bomb calorimeter. the reaction causes the temperature of a bomb calorimeter to decrease by 0.985 k. the calorimeter has a mass of 1.500 kg and a specific heat of 2.52 j/g•k. what is the heat of reaction for this system?

The heat of the reaction for the given system is -3723 J

Explanation:

The heat released by the reaction is absorbed by the calorimeter and the solution.

The chemical equation used to calculate the heat released follows:

where,

m = mass of the calorimeter = 1.500 kg = 1500 g    (Conversion factor:  1 kg = 1000 g)

c = heat capacity of calorimeter = 2.52 J/g.K

= change in temperature = 0.985 K

Putting values in above equation, we get:

Sign convention of heat:

When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.

Hence, the heat of the reaction for the given system is -3723 J
