AI Thread Summary
Enthalpy cycle problems in chemistry involve applying the conservation of energy principle to determine enthalpy changes during chemical reactions. The discussion highlights a user's difficulty in drawing an enthalpy cycle and understanding its components. Clarification is sought on the correct representation of enthalpy changes and the proper direction of arrows in the cycle. The user expresses uncertainty about their approach and the resulting chemical equation. Understanding the enthalpy cycle is crucial for solving related problems effectively.

What's an enthalpy cycle?

That means the enthalpy changing route
like what i have written for this question... but i believe i have done something wrong in that... because that doesn't seem to form the product as mentioned in the required chemical equation
 
Draw an arrow from top left to bottom right. What have you got?

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...
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...
