In the simulation, please perform the following actions to conduct the experiment: To begin: Navigate to the Rate Experiments tab. 1. Enter 100 in each box to specify the number of A and \( B \) reactant molecules. 2. Move the slider to adjust the temperature. So, you will perform the experiment in cold, hot, and room temperatures to see how it affects the reaction rate (molecules movement). 1. Move the slider to the center of the bar to turn it to room temperature. 2. Move the slider to the extreme right of the bar to turn it to hot temperature. 3. Move the slider to the extreme left of the bar to turn it to cold temperature. 3. Click the Begin Experiment button. Simultaneously, click to start the timer as well. 4. Notice the speed of the molecule movement and the count of molecules in the respective fields. 5. Click the End Experiment button, once the timer reaches 40 . 6. Note and record the count of the reactants and products molecules in the table below for question \#2.

Conducting an experiment with varying temperatures is a fantastic way to witness firsthand how reaction rates can change! Historically, scientists like Svante Arrhenius laid the groundwork for understanding how temperature influences reaction kinetics, establishing the Arrhenius equation to describe this behavior. So, as you conduct your simulations, remember you’re partaking in an experiment that echoes centuries of scientific inquiry! Once you've gathered your results, why not analyze them? A common mistake in interpreting reaction rates is neglecting to consider other factors that might influence molecule movement, like concentration or catalysts. Keep in mind that while temperature often plays a crucial role, the entire environment surrounding a reaction can modify the results. So, when drawing conclusions, take a holistic view of what you observe!
