 ChemPy is a Python package useful for chemistry (mainly
 physical/inorganic/analytical chemistry). Currently it includes:
 * Numerical integration routines for chemical kinetics (ODE solver front-end)
 * Integrated rate expressions (and convenience fitting routines)
 * Solver for equilibria (including multiphase systems)
 * Relations in physical chemistry:
   * Debye-Huckel expressions
   * Arrhenius & Eyring equation
   * Einstein-Smoluchowski equation
-* Properties (pure python implementations from the litterature)
+* Properties (pure python implementations from the literature)
   * water density as function of temperature
   * water permittivity as function of temperature and pressure
   * water diffusivity as function of temperature
   * water viscosity as function of temperature
   * sulfuric acid density as function of temperature & weight fraction H2SO4
