Hydrazine (N₂H₄) is used as a rocket fuel because it reacts very exothermically with oxygen to form nitrogen gas and water vapor. The heat released and the increase in number of moles of gas provide thrust. Calculate the enthalpy of reaction.

Respuesta :

The enthalpy of the reaction is ΔH = -543kJ/mol.

What is the enthalpy of reaction?

  • The difference between total reactant and total product molar enthalpies, computed for substances in their standard states, is the standard enthalpy of reaction for a chemical reaction.
  • As long as the enthalpy of mixing is taken into consideration as well, this can then be used to forecast the total chemical bond energy liberated or bound during the reaction.
  • A reaction's standard enthalpy is defined so that it solely depends on the conditions that are prescribed for it, rather than just on the actual circumstances in which reactions take place.
  • In these two situations, the heat effects have varied intensities.

we have written a chemical reaction for Hydrazine oxidation.

N₂H₄(l) + O₂(g) → N₂(g) +2H₂O(g)

m = total moles of reactant = 1 + 1 = 2

also specific heat = - 2.715

[tex]\Delta H = m\times s \times \Delta T[/tex]

[tex]\Delta H = 2 \times -2.715\times 100\\\Delta H = -543[/tex]

The enthalpy of the reaction is ΔH = -543kJ/mol.
