N2 + 3H2 3H2 -> 2NH3

A H = -92.2 kJ
During the above reaction, energy is -
A) absorbed
B) created
C) destroyed
D) released ​

Respuesta :

Given that the enthalpy change ΔH for the reaction is negative, energy is released during the reaction (Option D)

Data obtained from the question

  • Equation: N₂ + 3H₂ —> 2NH₃
  • Enthalpy change (ΔH) = –92.2 K
  • Nature of energy=?

How to determine the nature of the energy

From the data given above, we can see that the enthalpy change (ΔH) for the reaction is negative.

This simple means that heat energy is lost to the environment.

Therefore, we can conclude that the during the reaction, energy is released (Option D)
