The rate constant is highly variable in reactions and must be determined experimentally. The rate constant is dependent on both temperature and the presence of a catalyst. In a first-order reaction the rate constant and the half-life are both independent of the concentration and inversely proportional. Do you speak another language?

065 - The Equilibrium Constant In this video Paul Andersen defines the equilibrium constant (K) and explains how it can be calculated in various reversible reactions. The equilibrium constant is a ratio of the concentration of the products to the concentration of the reactants. If the K value is less than one the reaction will move to the left and if the K value is greater than one the reaction will move to the right. Do you speak another language?

This chemistry video tutorial provides a basic introduction into reaction mechanisms within a chemical kinetics setting. It explains how to write the rate law expression for a reaction mechanism. A reaction mechanism consist of a series of elementary steps or elementary reactions whose rate law can be written from its molecularity - that is from the coefficients of the balanced reaction. The rate of a reaction mechanism is completely dependent on the slow step or the rate-determining step. This video explains how to substitute an intermediate when writing rate law expressions. It contains plenty of examples and practice problems.

The rate law for 6I- + BrO3- + 6H+ --- 3H2O + Br- + 3I2 is determined using a clock reaction where the I2 reacts with thiosulfate until the thiosulfate runs out. Starch indicator is used to produce a blue color indicating that the iodine has reacted with all of the thiosulfate. The rate law is determined by mixing 10 mL of distilled water, 10 mL of 0.040 M KBrO3, 10 mL of 0.10 M HCl, 10 mL of 0.010 M KI and 10 mL of 0.0010 M Na2S2O3. In experiments 2-4, the amount of KI, KBrO3 and HCl are doubled and the distilled water is not added. This causes each to double in concentration for that experiment while all other concentrations remain constant. Finally the experiment is run with the same amounts as experiment #1, but at two different temperatures. This is used to measure the rate constants at these two temperatures in order to determine the activation energy for the reaction.

Here I look at 3 examples of how the rate equation can be obtained from experimental runs. The order of the reaction for each of the reactants is determined, allowing the rate equation to be constructed. In the third example I rearrange the rate equation to make the rate constant (k) the subject of the equation. I then work out its value and units. In the next video "Kinetics 2" I look at 3 further examples, which are a little more difficult.

In this video you will learn how to plot the concentration of reactants vs time to determine the rate order and rate constant of a chemical reaction. This is accomplished by using integrated rate laws. For example, if a plot of concentration vs time is linear, then the reaction is a zeroth order reaction and the slope of the best fit line is the rate constant (times negative 1). If a plot of the natural log of concentration vs time is linear, then the reaction is first order and the slope is once again the rate constant (times negative 1). Lastly, if the plot of one over concentration vs time is linear, then the reaction is second order and the rate constant is the slope (not negative in this case).

This chemistry video tutorial provides a basic introduction into the collision theory model. In order for two molecules to react, they must collide with sufficient energy and with the proper molecular orientation. This video describes the relationship of the rate of the reaction with temperature and activation energy using the arrhenius equation. As the temperature increases, the rate constant k increases, which in turn increases the rate of the reaction. Whenever a catalyst is added, the activation energy decreases which increases the value of the rate constant k which in turn increases the reaction rate. This video also includes a brief discussion into energy diagrams. The forward activation energy is the difference between the energy of the transition state / activated complex and the energy of the reactants. This video is part of the chemical kinetics series. This tutorial also discusses the difference between the collision frequency, steric factor, and the frequency factor in the arrhenius equation.
