Question

2 define standard enthalpy of formation.writeachemical equation for the formation of n2o5

Answer 1

Hey there
The standard enthalpy of formation isdefined as the change in enthalpywhen one mole of a substance in thestandard state is formed from its pure elements under the same conditions.
The chemical equation for the formation of n2o5 is
N2 (g) + 5/2 O2 (g) --> N2O5 (g)
