Q6 Ig of graphite is burnt in a bomb calorimeter in excess
of oxygen at 298 K and 1 atmospheric pressure according
to the equation C (graphite) + O2(g) → CO2 (g) During
the reaction, temperature rises from 298 K to 299 K. If
the heat capacity of the bomb calorimeter is 20.7kJ/K,
what is the enthalpy change for the above reaction at
298 K and 1 atm?
Q7 the conversion of one mole of benzene takes place at
298 K and 1 ATM after combustion, CO2(g) and H20 (1)
are produced and 3267.0 kJ of heat is liberated. Calculate
the standard enthalpy of formation, A,H® of benzene.
Standard enthalpies of formation of CO2(g) and H2O(1)
are -393.5 kJ mol and - 285.83 kJ mol- respectively.

Answer:
Hess's law, also called Hess's law of constant heat summation or Hess's law of heat summation, rule first enunciated by Germain Henri Hess, a Swiss-born Russian chemist, in 1840, stating that the heat absorbed or evolved (or the change in enthalpy) in any chemical reaction is a fixed quantity and is independent of the ...
