On what principle does calorimetry depends
law of conservation of energy.
What processes are endothermic
During an endothermic process heat is absorbed.
How can an unknown H reaction be determined using Hess law
To use Hess Law, one simply uses the known equations and their respective ∆H values, rearranges them as necessary to arrive at the target equation (unknown ∆H) and then adds the ∆H values to obtain the value for the target equation. This is possible because Hess Law applies to state functions which are independent of the path.
