Chemical reactions are invariably associated with transfer of energy miner  in form of heat or light. In the laboratory, heat changes in physical and chemical processes are measured with an instrument called calorimeter. Heat change in the process is calculated as
q = ms Δ T                s = specific heat J/K-gm
=C Δ T                          C = heat capacity J/K
In Bomb calorimeter measurement are taking at constant volume.
So heat of reaction at constant volume :
q = ΔU (Internal energy change)
Here heat is released by combustloin so sign of AU and heat should be negative. In water colarimeter measurement are taking at constant pressure.
So, qp = Δ H
qp = qv + P Δ V
Δ H = Δ U + Δ ngRT
Match the list-I and list-II and select the answer : List-I (Unbalanced reaction)
