Solution

The correct option is A 1
All combustion reactions are exothermic. For such reaction, the enthalpy change is negative $Δ H = - v e$ . The enthalpy of reactants is greater than the enthalpy of products.
For example, the enthalpy change associated with combustion of 1 mole of carbon is $- 94 k c a l .$
