equidistribution
- n a flat distribution having equal frequencies of occurrence
equilibrium
- n a stable situation in which forces cancel one another
- n a chemical reaction and its reverse proceed at equal rates
- n equality of distribution
- n a sensory system located in structures of the inner ear that registers the orientation of the head
equilibrium constant
- n (chemistry) the ratio of concentrations when equilibrium is reached in a reversible reaction (when the rate of the forward reaction equals the rate of the reverse reaction)
equilibrium law
- n (chemistry) the principle that (at chemical equilibrium) in a reversible reaction the ratio of the rate of the forward reaction to the rate of the reverse reaction is a constant for that reaction
equine distemper
- n an acute bacterial disease of horses characterized by inflammation of the mucous membranes
equine encephalitis
- n encephalitis caused by a virus that is transmitted by a mosquito from an infected horse
equine encephalomyelitis
- n encephalitis caused by a virus that is transmitted by a mosquito from an infected horse

equinoctial point
- n (astronomy) either of the two celestial points at which the celestial equator intersects the ecliptic
equinoctial year
- n the time for the earth to make one revolution around the sun, measured between two vernal equinoxes
equinox
