radioactivity
Involves the release of particles and/or energy from the nucleus of an atom.
Raoult’s Law
States that vapor pressure of a solution equals the product of the vapor pressure of the pure solvent and the
mole fraction of solvent, as described by: P = xsolventP°.
reactant-favored equilibrium
At the equilibrium, the concentration of products is small and the concentration of reactants is large.
reaction mechanism
Follows a reaction pathway going from initial reactants to final products. Describes the intermediate steps in
a reaction.
reaction quotient
A function of the actions of a chemical species in a chemical reaction. The symbol for this is Q.
reaction rate
The change in concentration of a reactant or product with time.
reaction yield
The amount of product that is actually produced in a given chemical reaction.
reactor
Nuclear reactors heat water to steam to drive a turbine for generation of electricity.
reducing agent
Causes a reduction of another species in the reaction.
reduction
The gain of hydrogen, the loss of oxygen, or the gain of electrons.
RNA
Ribonucleic acid. The single-stranded polymer is also composed of bases linked by phosphate bridges.
