# Reaction Mechanisms

### Some Flash animations of reaction mechanisms:

Here are three possible mechanisms for the reaction:

$$\ce{CO(g) + NO2(g) \rightarrow CO2(g) + NO(g)}$$

Each animation repeats in a loop.
Click the red box to pause the animation; click the green box to continue.
Refresh the page to start an animation from the beginning.

## Single step mechanism

This animation illustrates what the mechanism would look like if it occurred in a single step.

## Two step mechanism #1

This animation illustrates a possible two step mechanism and shows how the two steps add up to give the overall reaction. It includes a catalyst which is used and then regenerated.

## Two step mechanism #2

This animation illustrates another possible two step mechanism and asks what the two steps are.
