Document Summary
Chapter 15: introduction to reaction rates and rate. Regards the speed of reactions and how reactions occur, microscopically. The understanding of kinetics can be applied to the environment; slow down or turn off mechanisms that are damaging to the environment (pollution). Development of better technologies: increase the speed of reactions: pervades all aspects of industry. Average speed: distance over time: more specifically, the change in distance over the change in time. Instantaneous speed: the speed of an object at a given time: chemical reactions occur at fluctuating speeds; its average speed is not its speed the entire time, slope of tangent line to curve at that point. The geometric rate at that point in time. In chemistry, it is not distance over time but change in concentration over the change in time: how much is the rate changing as a result of the reaction, ex: The rate of which no2 is used. The rate of which oxygen gas is formed.
