Find δerxn for the combustion of naphthalene. the heat capacity of the calorimeter, determined in separate experiment, is 5.11kj/∘

c.

Combustion of naphthalene in the calorimetric bomb occurs at constant volume. Thus, change of system’s internal energy during the reaction will be equal to the amount of produced heat:

ΔrU = Q = CV·ΔT = 5.11· (32.33 - 24.25) = 41.3 kJ
