Calculate the value of Kc for the dissociation reaction

AI Thread Summary
At 77°C, 2 moles of nitrosyl bromide (NOBr) dissociate by 9.4% in a 1-liter flask. This results in 1.188 mol of NOBr remaining after dissociation. The dissociation reaction is represented as 2NOBr (g) = 2NO (g) + Br2 (g). To calculate Kc, the concentrations of the products and remaining reactants must be determined based on the initial amount and the extent of dissociation. Providing detailed work is encouraged for clarity in problem-solving.

[SOLVED] need help

At 77°C, 2 mols of nitrosyl bromide, NOBr, placed in a 1 liter flask dissociates to
the extent of 9.4%; that is, for each mol of NOBr before reaction, (1.000-0.094) mol
NOBr remains after dissociation. Calculate the value of Kc for the dissociation
reaction. 2NOBr (g) = 2NO (g) + Br2 (g)

do your own hw
 
I did, but i duno about these 4 problems.
 
I think what GNW is telling you is to follow the form given when asking for help in this forum and please do show some work.
 
i see
 
forget it, I don't need the help anymore.

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...
