The Rate Constant
 
06:53
037 - The Rate Constant In this video Paul Andersen describes the characteristics of the rate constant in chemical reactions. 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?

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.

Reaction Rates, Chemistry & Kinetics, Instantaneous vs Average Rate of Reaction
 
06:23
This chemistry video tutorial provides a basic introduction into reaction rates. The rate of reaction can be calculated from the slope of a concentration vs time graph. The slope of the secant line is equivalent to the average rate of the reaction. You can calculate the slope with the average rate of reaction formula using the data from a graph. The instantaneous rate of reaction over a time interval is equal to the slope of the tangent line. This video is part of the chemical kinetics series. It contains plenty of examples and practice problems of calculating the average rate of appearance of products and the average rate of disappearance of reactants. The production rates of products will always be positive as the reaction proceeds in the forward direction and the rate of consumption of reactants will always be negative.

Consider the equation for the decomposition of SO2Cl2. SO2Cl2 (g) → SO2 (g) + Cl2 (g) The concentration of SO2Cl2 is monitored at a fixed temperature as a function of time during the decomposition reaction, and the following data are tabulated: (a) Show that the reaction is first order and determine the rate constant for the reaction. (b) Use the graph and the best fitting line in the previous example to predict the concentration of SO2Cl2 at 1900 s. The First-Order Integrated Rate Law: Using Graphical Analysis of Reaction Data The plot is linear, confirming that the reaction is indeed first order. To obtain the rate constant, fit the data to a line. The slope of the line is equal to −k. Since the slope of the best fitting line (which is most easily determined on a graphing calculator or with spreadsheet software such as Microsoft Excel) is −2.90 × 10−4s−1, the rate constant is therefore +2.90 × 10−4s−1.

How to determine the rate of change using a graph

Learn how to find the rate of change from graph. The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph such that the line of the graph is the hypothenuse of the right triangle. Then the rate of change of the graph is given by the length of the vertical leg of the right triangle divided by the length of the horizontal leg of the right triangle. #linearequations #sloperateofchange

Finding rate constants and order with excel 2013 - Real Chemistry
 
09:04
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).
