Determine the signs of ∆H, ∆G, ∆S for the reaction: N2(g) → 2N(g)

Click For Summary
SUMMARY

The discussion focuses on the thermodynamic properties of the reaction N2(g) → 2N(g), specifically the signs of ΔH, ΔG, and ΔS. It is established that the reaction involves the dissociation of molecular nitrogen into atomic nitrogen, which is an endothermic process, indicating a positive ΔH. The reaction's spontaneity is questioned, leading to the conclusion that ΔG is also positive under standard conditions, reflecting non-spontaneity. Additionally, the increase in entropy due to the formation of two moles of gaseous nitrogen atoms from one mole of nitrogen gas results in a positive ΔS.

PREREQUISITES
  • Understanding of thermodynamic principles, specifically Gibbs free energy.
  • Familiarity with enthalpy and entropy concepts.
  • Knowledge of reaction spontaneity and equilibrium.
  • Basic grasp of molecular versus atomic forms of elements.
NEXT STEPS
  • Study the relationship between ΔH, ΔG, and ΔS in thermodynamics.
  • Explore the concept of reaction spontaneity in detail.
  • Investigate the phase behavior of nitrogen under various conditions.
  • Learn about the implications of entropy changes in chemical reactions.
USEFUL FOR

Chemistry students, educators, and professionals interested in thermodynamics and reaction mechanisms.

Homework Statement
Determine the signs of ∆H, ∆G, ∆S for the reaction: N2(g) → 2N(g) Assume standard conditions and temperature = 25 oC
Relevant Equations
∆G=∆H-T∆S
Hello are you able to explain the two incorrect ones. I am not sure how to do this as there is no phase change involved, nor is there a temperature or volume change.
