When `1g` liquid naphthalene `(C_(10)H_(8))` solidifies, `149J` of heat is evolved. Calculate the enthalpy of fusion of naphthalene.

When '1 g' of liquid naphthalene '(C_(10) H_8)' solidifies, '149 J' of heat is evolved. Calculate the heat of fusion of naphthalene.

The heat of combustion of solid naphthalene. (C_(10)H_(10)) at constant volume was -4984kJmol^(-1) " at " 298K. Calculate the value of enthalpy change. Given: C_(10)H_(8_((s)))+120_(2_((g)))rarr10CO_(2_((g)))+4H_(2)O_((l)),DeltaU=-4984 kJ.mol^(-1) DeltaU=-4984 kJmol^(-1),R=8.314JK^(-1)mol^(-) T=298K

Change in enthalpy and change in internal energy are state functions. The value of DeltaH, DeltaU can be determined by using Kirchoff's equation. I mole of naphthalene (C_(10)H_(8)) was burnt is oxygen gas at 25^(@)C at constant volume. The heat evolved was found to be 5138.8kJ. Calculate the heat of reaction at constant pressure
