Reaction Rates (Kinetics)

Reaction Rates (Kinetics)

Reaction Rates (Kinetics). Chapter 16. Big Picture. Thermodynamics (energy) tells us in which direction a change occurs e.g. does a ball roll up or down a ramp? Kinetics (reaction rates) tells us how fast a change occurs e.g. what is the speed of the ball rolling down a ramp?.

How do nuclear decay rates differ from chemical reaction rates?

How do nuclear decay rates differ from chemical reaction rates?

These stone tools from the archaeological site in Cactus Hill, Virginia, are at least 15,000 years old. Scientists estimated the age of the site based on rates of nuclear decay. Half-life. How do nuclear decay rates differ from chemical reaction rates?.

Heterogeneous Catalysis by Supported Metals

Heterogeneous Catalysis by Supported Metals

Heterogeneous Catalysis by Supported Metals. By far the most widely used industrial catalysts are heterogeneous formulations of inorganic solids. Zeolites and clays are widely used in cracking processes, and similar materials are employed as supports for finely dispersed metals.
