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.

how to determine the order of a reaction by the initial rates method
 
05:23
This video-tutorial shows how to determine the order of a reaction by the initial rates method. The most common method for directly determining the order of a reaction - the form of the rate law - is the method of initial rates. https://youtu.be/7Y8fc0SS-ws Several experiments are carried out using different initial concentrations and the initial rate is determined for each run. The results are then compared to see how the initial rate depends on the initial concetrations. The initial rates method shows the effect of varying reactant concentrations on the initial rate of reaction. Using this data we can determine the order with respect to each reactant, and hence the rate equation.
