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.

Q8 explain

 Hess law

 Born haber cycle

 Gibbs energy

 Diagnol relationship of li​

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 ...
