Highschool chemistry question on Le Chatlier's Principle

AI Thread Summary
Adding reactant A to the equilibrium reaction A(aq) + B(aq) <-> C(aq) will shift the equilibrium position to the right, resulting in an increase in the concentration of A and a decrease in the concentration of C at the new equilibrium. According to Le Chatelier's Principle, the system will adjust to counteract the change in concentration of A. This principle emphasizes that changes in concentration will prompt the system to shift in a direction that reduces that change. Formulating the equilibrium equations and applying the conservation of mass can provide further insights into the system's behavior. Understanding these concepts is crucial for mastering equilibrium reactions in chemistry.

Homework Statement


I just have a concept question on LCP.
in reaction: A(aq) + B(aq) <-> C(aq)
A is added and rxn is left to reach a new equilibrium.
Once @ new eqm, is [A] higher than before? and obviously [C] is lower, right?

I hope you will get to a point where the opposite is obvious.

"Changing the concentration of an ingredient will shift the equilibrium to the side that would reduce that change in concentration. The chemical system will attempt to partially oppose the change affected to the original state of equilibrium."

It will probably help if you can formulate the equations, equilibrium equations + conservation of mass and see what they tell you.

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...
