AI Thread Summary

An exothermic reaction is a chemical process that releases heat, resulting in an increase in the temperature of the surroundings. In contrast, an endothermic reaction absorbs heat, leading to a decrease in the temperature of the surroundings. Heat refers to the energy transferred between systems due to temperature differences, while temperature measures the average kinetic energy of particles in a substance. The three laws of thermodynamics describe the conservation of energy, the direction of energy transfer, and the concept of absolute zero, where all molecular motion ceases. Understanding these concepts is crucial for grasping the principles of energy transfer and transformation in physical and chemical processes.

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...
