High-purity benzoic acid (C6H5COOH; DHcomb = -3227 kJ/mol) is a combustion standard for calibrating bomb calorimeters. A 1.221-g sample burns in a calorimeter (heat capacity = 1365 J/degC) that contains exactly 1.200 kg water. What temperature change is observed?© BrainMass Inc. brainmass.com March 4, 2021, 6:02 pm ad1c9bdddf
To answer these types of questions it is useful to use this equation.
nDHcomb = DT(Cbomb + mCwater)
n = moles of substance being tested in the ...
The solution employs one very useful equation from the relevant theory to solve for the temperature change observed when burning a sample of benzoic acid in a bomb calorimeter containing exactly 1kg of water to calibrate it.
