Chemical Kinetics Homework: Ineq., Mass & English

AI Thread Summary
The discussion centers on the relationship between concentration and mass in the context of the chemical kinetics equation ln[A] = -kt + ln[A]0. It questions whether mass can be substituted for concentration in the equation. The response clarifies that while concentration is typically used, mass can be factored into the rate constant (k) if the volume and molar mass remain constant. This allows for the use of mass in calculations without altering the fundamental kinetics principles. Understanding this relationship is crucial for solving related homework problems effectively.

Homework Equations

ln[A]=-kt+ln[A]0

The Attempt at a Solution


In this equation,is it necessary to have [A] to be the concentration?
If there is the mass provided only,can I just subsitute [A]=mass?

Sorry for my poor english

It is about concentration. However, for a constant volume (and taking into account molar mass is constant for a given substance) you can be able to factor them out into k constant. That is just a simple math.

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...
