Concentration and pressure are really important when it comes to how fast reactions happen in gases. This is because they both affect how often particles bump into each other.

When the concentration is higher, there are more particles in a small space. This means they can collide with each other more often.

Here’s an example:

• More Concentration: If you double the amount of reactants, the chances of collisions also double.

Now, let’s talk about pressure. When you increase the pressure in a gas, it makes the gas take up less space. This also makes it easier for particles to bump into each other.

To sum it up:

• More particles = more bumps into each other = faster reactions!
