How does the hydrogen ion (H+) [or the hydronium ion (H3O+)] and the hydroxide ion (OH-) fit into all of this? What is their role in this reaction?
The box is then heated to 500K, which causes the ammonia to partially decompose to Nitrogen and Hydrogen and results in a final pressure of 4.85*10^6 pa. Find the number of moles and partial pressure of all three gases at 500K. What is the average..
