Trick: Create two new columns, ln[A] (1st order) and 1/[A] (2nd order), then calculate first differences. Whichever set of first differences is approximately constant .... that corresponds to the order of your reaction.

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.

How to determine the rate law from a table of trials - Real Chemistry
 
11:26
In this video you will use the method of initial rates to determine the rate law for the decomposition of ozone. The method of initial rates involves using a series of experiments (trials) where you measure the concentrations of different chemical species and measure the rate of the reaction. If these trials are done multiple times you can use the data to determine the rate law. For example, if trial 2 doubles the concentration of reactant A compared to trial 1 and this doubles the reaction rate, we can say that the reaction is 1st order with respect to reactant A. If trial 3 doubles the concentration of just reactant B and this quadruples the rate, we can say that the reaction is 2nd order with respect to reactant B.

Kinetics 1: Finding the Order, Rate Equation & Rate Constant
 
08:45
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.

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).

04:04
Examination of rate data will show relationships between the [reactants] and the rate of reaction. If the rate does not change when the [reactant] does -- the order of reaction will be zero for this reactant. A directly proportional relationship gives an order of one, and a squared relationship gives a two. Units for k will vary with the order of reaction; 1st order gives s-1, 2nd order mol-1 dm-3 s-1, 3rd order mol-2 dm6 s-1.
