AI Thread Summary
The discussion focuses on calculating the rate of oxygen (O2) release from the decomposition of potassium chlorate (KClO3). Given that 0.20 g of KClO3 decomposes in 2.8 seconds, the rate of decomposition is calculated to be 0.000583 mol/s. Participants mention the need to apply the ideal gas law (n = PV/RT) to determine the rate of O2 produced at standard ambient temperature and pressure (SATP). The conversation highlights the conversion of KClO3 to moles and the subsequent calculations leading to the rate of decomposition. Further assistance is sought to complete the calculation for the rate of O2 release.

Homework Statement



2 KClO3 (s) + heat --> 2 KCl (s) + 3 O2 (g)

If 0.20 g of KClO3 (s) decomposes in 2.8 s, at what rate is oxygen O2 (g) released over this time at SATP?

Homework Equations



n = PV/RT

The Attempt at a Solution



Converted KClO3 to mol.

.20 x 1 / 122.5495g = 0.001632 mol KCl

Find rate of decomposition :

.001632 mol in 2.8 sec --> 2 mol in 3431.37 sec

2/3431.37 = .000583 mol/s

The rate of decomposition of KClO3 is .000583 mol/s

I'm stuck at this part. I know I need to use some sort of n = PV/RT since it tells me that it is at SATP. Can I have some hints or help?

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...
