<center><b>Two Pillars of Chemical Reactions : Kinetic and Thermodynamics</b></center> <br> In a chemical reaction, there are three questions that are commonly asked?<br> <br> 1. Does this chemical reaction occur?<br> 2. How fast is the chemical reaction or how fast are the products formed (called <b>rate of reaction</b>)?<br> 3. How do the reactants rearrange to make the product (called <b>reaction mechanism</b>)<br> <br> <br> <b>Thermodynamics</b> is the study of the movement (-dynamic) of heat/energy (thermo-) in chemical reaction. Almost all chemical reaction have either a total gain of heat/energy (or total loss of heat/energy) as the chemical reaction proceeds. This change in heat/energy determines if the chemical reaction occurs or not. Therefore, <b>Thermodynamics answers Question #1</b> or <i>does the chemical reaction occurs or not.</i> It does not. however, explain how fast or the reaction mechanism of the chemical reaction.<br> <br> How fast and what is the reaction mechanism for a chemical reaction is the domain of <b>Kinetics</b>. Therefore, <b>Kinetics answers Question #2 & #3</b> and will be the topic we will deal with now.<br> <br> <br> ?Why do reactants form products? <b>Smashmouth approach</b> <br> <br> <br> Effective Collisions<br> <br> <br><br> Two factors for a effective collision:<br> <br><br> <br> <b>DEMO</b>
