Interpretation:
The volume of ethane that is required to heat the mass of water has to be given.
Concept Introduction:
The change in enthalpy that is associated with the formation of one mole of a substance from its related elements being in standard state is called standard enthalpy of formation
(
The standard enthalpy of reaction is the enthalpy of reaction that takes place under standard conditions.
The equation for determining the standard enthalpies of compound and element can be given by,
Specific heat:
Specific heat can be defined as quantity of heat required to raise the temperature of
Where
c= Specific heat
The unit of specific heat is
