Hey everyone, I'm in a little pickle if I must say. I've got this question on my assignment asking me to explain what the physical and chemical characteristics of a "gas" equilibrium whilst explaining the forward/reverse reactions and their dynamic nature. My problem, what is a "gas" equilibrium? Is it the same as a normal equilibrium? I'm also not sure what characteristics are, is it when the forward reaction is equal to the reverse reaction? Also on another question, it asks to explain how the equilibrium constant is calculated and I'm fine with that, but its sorta bugging me how they came up with the equation. where K=[products]/[reactants] Can anyone explain it to me in not so difficult terms?
