Given the following thermochemical equation: CaCOa(s) → CaO(s) +CO2 (g) AH=177.8 kJ/mol What is the change in the internal energy for the reaction (AE) if 152-grams of CaCO3(s) is decomposed into CaO(s) and that CO2(g) produced expanded from 2.0 L to 3.5 L against a pressure of 12.3 atm? Note: For the heat absorbed by the system, use the amount of heat absorbed in the chemical reaction.
