Frank-Kamenetskii theory
So, imagine you have a toy castle made of blocks. These blocks can stick together because they have little bumps and holes that fit together very well.
Now, let's say you wanted to build a bigger castle by adding more blocks to it. But, you notice that some of the blocks you add are bigger or smaller than the ones you already had, and they don't fit together well anymore.
This is sort of like what happens when you heat up or cool down some materials. When you heat them up, the atoms or molecules inside get excited and start moving around a lot. When you cool them down, they slow down and move less.
The Frank-Kamenetskii Theory is a way that scientists can understand how materials change and react when you heat them up or cool them down. It helps them figure out how the atoms and molecules will move and how they will react with each other.
In other words, it's like knowing which blocks will fit together well no matter what size they are, so you can build the biggest and strongest castle possible!
