How to Interpret Solid-Liquid Phase Diagrams for Mixed Metal Oxide Systems?

AI Thread Summary
The discussion focuses on interpreting solid-liquid phase diagrams for mixed metal oxide systems, specifically the XO-ZO system. The user is confused about the terminology "halt" and "break" temperatures and seeks clarification on how to construct the phase diagram based on provided cooling curve data. Feedback indicates that the user's diagram may not accurately represent the relationship between break temperature and composition. There is a suggestion that "halt" could refer to a phase change, but the user needs further guidance to correct their diagram. Overall, the conversation highlights the challenges in understanding and accurately depicting phase diagrams in materials science.

The Attempt at a Solution


I don't understand why the temperatures are called "halt" and "break" but I came up with this diagram. My professor and the textbook don't explain how to make these diagrams so I'm totally lost. Can someone check this and if its wrong help me correct it?

Halt may mean that it undergoes a phase change. Assuming that your graph is supposed to be the break temperature versus the composition your plot does not seem correct.

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...
