We're asked to calculate the ΔH°f for IF for the reaction:
IF7(g) + I2(g) → IF5(g) + 2 IF(g) ΔH°rxn = -89 kJ
Recall that we can calculate the enthalpy of formation (ΔH˚f) of IF from the given ΔH˚rxn using the equation:
Use the ΔH°f and ΔH°rxn information provided to calculate ΔH°f for IF.
IF7(g) + I2(g) → IF5(g) + 2IF(g) ΔH°rxn = -89kJ
b. 101 kJ/mol
c. -95 kJ/mol
d. -190 kJ/mol
e. -146 kJ/mol
