Activation Energy
 
04:52
039 - Activation Energy In this video Paul Andersen explains how the activation energy is a measure of the amount of energy required for a chemical reaction to occur. Due to the collision theory the activation energy requires proper energy and orientation of the colliding molecules. The Maxwell-Boltzman distribution can be used to determine the number of particles above and below this point. Do you speak another language?

Activation energy may also be defined as the minimum energy required to start a chemical reaction. The activation energy of a reaction is usually denoted by Ea and given in units of kilojoules per mole. Activation energy can be thought of as the height of the potential barrier (sometimes called the energy barrier) separating two minima of potential energy (of the reactants and products of a reaction). For a chemical reaction to proceed at a reasonable rate, there should exist an appreciable number of molecules with energy equal to or greater than the activation energy. At a more advanced level, the Arrhenius Activation energy term from the Arrhenius equation is best regarded as an experimentally determined parameter that indicates the sensitivity of the reaction rate to temperature. There are two objections to associating this activation energy with the threshold barrier for an elementary reaction. First, it is often unclear as to whether or not reaction does proceed in one step; threshold barriers that are averaged out over all elementary steps have little theoretical value. Second, even if the reaction being studied is elementary, a spectrum of individual collisions contributes to rate constants obtained from bulk ('bulb') experiments involving billions of molecules, with many different reactant collision geometries and angles, different translational and (possibly) vibrational energies - all of which may lead to different microscopic reaction rates.

How Do Enzymes Work? (Activation Energy)
 
06:49
Enzymes speed up (catalyse) chemical reactions by lowering the amount energy required to start the reaction. The energy required to start the reaction is called activation energy. Enzymes lower activation energy by either putting strain on the chemical bonds of a substrate molecule or bringing substrate molecules (reactants) together in the correct orientation so that they react more readily.

General Organic Chemistry-Part 6a-Introduction to Intermediates & Transition States
 
22:09
An intermediate is a short-lived unstable molecule in a reaction which is formed inbetween the reaction when reactants change into products. Whereas, transition state is just the state before formation of new molecule(involves breaking of bonds of reactants and formation of new ones) An intermediate differs from a transition state in that the intermediate has a discrete lifetime (be it a few nanoseconds or many days), whereas a transition state lasts for just one bond vibration cycle. Intermediates may be unstable molecules (in which case they are called reactive intermediates) or highly stable molecules. The difference between them can be better described through the energy profile diagram. In this Video I describe in detail the concept of Intermediates & Transition Sates. Transition states are local energy maximums and have partial bonds. This might be one of the reasons why they cant be isolated as intermediates.

A catalyst is a chemical that appears as a reactant first, and then as a product. It has been regenerated and doesn't appear in the overall reaction. An intermediate is a chemical that appears as a product first, and then as a reactant. It was produced, but it consumed before the reaction is over. It also doesn't appear in the overall reaction.

Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

Chemical Kinetics 2.9 - Reaction Coordinates
 
05:12
Short lecture on the reaction coordinates and transition states of chemical reactions. The reaction coordinate gives the energy of a compound as a function of its transition from reactant to product. The maximum energy occurs at the transition state. The activation energy is the difference in between the reactant and the transition state.
