Question

The same reaction, with exactly the same amount of reactant, is conducted in a bomb calorimeter and in a coffee-cup calorimeter. In one measurement, qrxn=−13.2qrxn=−13.2 kJkJ in the other qrxn=−11.7qrxn=−11.7 kJkJ. Which value was obtained in the bomb calorimeter? (Assume that the reaction has a positive ΔVΔV in the coffee-cup calorimeter.)
