The standard heat of combustion of solid naphthalene `[C_(10)H_(8)(s)]` at `25^(@)C` is -5147`kJ*mol^(-1)`. What does it mean?

Text Solution

Verified by Experts

At `25^(@)C` , the standard heat of combustion of solid naphthalene `[C_(10)H_(8)(s)]` is -5147 `kJ*mol^(-1)`. This means that at `25^(@)C` and 1 atm presure when 1 mol of solid nephthalene is completely burnt in presence of oxygen, the enthalpy change that occurs is -5147 kJ.
