Chemical Kinetics

Chemical Kinetics. The area of chemistry concerned with the speeds, or rates, at which a chemical reaction occurs. Reaction Rate. The reaction rate is the change in the concentration of a reactant or a product with time, (M/s or M . s -1 ), where M is molarity and s represents seconds.

Vacuum Systems

Vacuum Systems. Why much of physics sucks. Why Vacuum?. Anything cryogenic (or just very cold) needs to get rid of the air eliminate thermal convection; avoid liquefying air Atomic physics experiments must get rid of confounding air particles eliminate collisions
