Step 1 of 5) Effect of concentration on reaction rate. The difference in behavior is due to the different concentrations of O2 in the two environments.The speed of an event is defined as the change that occurs in a given time interval, which means that whenever we talk about speed, we necessarily bring in the notion of time. For example, the speed of a car is expressed as the change in the car’s position over a certain time interval. In the United States, the speed of cars is usually measured in units of miles per hour—that is, the quantity that is changing (position measured in miles) divided by a time interval (measured in hours). Similarly, the speed of a chemical reaction—its reaction rate—is the change in the concentration of reactants or products per unit of time. The units for reaction rate are usually molarity per second 1M>s2—that is, the change in concentration measured in molarity divided by a time interval measured in seconds.
