Question

the enthalpy change for the reaction 2H2 +
O2--> 2H2O is 574kJ what is the heat of
formation of water

Akanksha C. · Accepted Answer

Dear Student,
Heat of reaction = [the sum of all heats of formation of all
products] - [the sum of all heats of formation of all
reactants]

Enthalpy of the reaction = 574 KJ

So the heat of formation of water = 574/2 = 287 KJ ( for 1 mole of
water)
