Answer 1

ΔHrxn can be calculated from the heats of formation of each substance in the equation in their standard state.

ΔHrxn is a thermodynamic function.

A state function is independent of reaction pathway.

ΣnHf0 products - ΣnHf0 reactants = ΔHrxn

A bond forming process is always exothermic.

A bond breaking process is always endothermic.

Molar heat of reaction can be estimated from bond energies.

Calculating bond energies can be done only for gas phase compounds.

Triple bonds have the highest bond energies.

Higher bond energies reflect more stable bonds.
