The discussion focuses on determining the signs of ΔH, ΔG, and ΔS for the reaction N2(g) → 2N(g). Participants note that there is no phase change, temperature, or volume change, complicating the analysis. The presence of diatomic nitrogen (N2) in nature suggests that the reaction is not spontaneous, indicating a positive ΔG. The breakdown of N2 into atomic nitrogen (N) is endothermic, leading to a positive ΔH. Overall, the reaction is characterized by an increase in entropy, resulting in a positive ΔS.

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.

Which form of nitrogen do you find in nature? What does that tell you about the ΔG of the given reaction?

Thread 'Coulomb's force vs the Lorentz force'

Beams of electrons and protons move parallel to each other in the same direction. They ______. a. attract each other. b. repel each other. c. neither attract nor repel. d. the force of attraction or repulsion depends upon the speed of the beams. This is a previous-year-question of CBSE Board 2023. The answer key marks (b) as the right option. I want to know why we are ignoring Coulomb's force?
