Chemical Equilibrium Q: How Does Solution (a) Know PH2S=Ammonia?

AI Thread Summary
The discussion centers on understanding how solution (a) recognizes that the partial pressure of H2S equals that of ammonia. It highlights that prior to adding H2S, the stoichiometry of the dissociation reaction ensures that the partial pressures of H2S and NH3 are equal. This relationship is crucial for achieving chemical equilibrium. The participants acknowledge the importance of stoichiometry in this context. Overall, the conversation clarifies the role of stoichiometric principles in chemical equilibria.

I have a question about the solution (a) in this example, how does it know PH2S is the same as ammonia? is there something I've miss?

Before adding H2S, the partial pressures of H2S and NH3 are equal because of the stoichiometry of the dissociation reaction.

Oh yeah, I totally forgot about that. Thanks for your help :D

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
