Rat of reaction problems i have no idea how to do

AI Thread Summary
To determine the rate of a chemical reaction at 55°C, the Arrhenius equation is typically used, but insufficient information is provided for its application. A common rule of thumb suggests that the reaction rate approximately doubles for every 10°C increase in temperature. Given the initial rate of 280 M/s at 45°C, it can be estimated that the rate at 55°C would be around 560 M/s. This method is an approximation and should be treated as such. Understanding the limitations of this approach is crucial for accurate calculations.

A certin chemical reaction is carried out at 45C and the rate observed is 280M/s. What will the rate of the reaction be at 55C?

i have no idea what equation to use for this problem could someone break it down for me step by step

In general this type of questions is solved with Arrhenius equation. However, you are not given enough information to use it.

My bet is that you are expected to use a rule of thumb that states that reaction gets twice faster when temperature grows by 10 deg C. Just remember that this is an approximation of approximation :wink:

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...
