Which Cell Reaction Will Form More Products at Equilibrium?

AI Thread Summary
A positive E° value indicates a spontaneous reaction, favoring product formation at equilibrium, while a negative E° value suggests non-spontaneity. The relationship between the equilibrium constant (K) and E° can be described by the equation ΔG° = -nFE°, where a positive E° leads to a larger K, indicating more products. Therefore, the cell reaction with the positive E° value will form more products at equilibrium. Understanding this relationship is crucial for predicting reaction outcomes. Mastery of these concepts is essential for success in the upcoming exam.

Homework Statement


The E° value of one cell reaction is positive and that of another cell reaction is negative. Which cell reaction will proceed toward the formation of more products at equilibrium?

Homework Equations


E° cell = E° cathode - E° anode

I have an exam on Friday and I can't really see how which one would form more products in equilibrium, and that worries me. Please help. :(

Do you know any equations that relate the equilibrium constant (K) to the E° value of your reaction?

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...
