  1. 3. energy the minimum amount of energy that must be provided for compounds to result in a chemical reaction. the change in enthalpy associated with a particular chemical process any chemical substance produced during the conversion of some reactant to a product
  2. 5. a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously
  3. 11. the branch of physical chemistry that is concerned with understanding the rates of chemical reactions.
  4. 12. The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.
  5. 13. reaction in which products are produced from reactants and it goes from left to right in a reversible reaction
Down
  1. 1. used to relate the free energy changes that occur during the progress of chemical processes to the rate and equilibrium constants of the process
  2. 2. any chemical reaction that absorbs heat from its environment
  3. 4. the movement of one or more components of a mixture to improve contact
  4. 6. a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity, or sound
  5. 7. he average kinetic energy of all the atoms or molecules of that substance
  6. 8. he energy change in an overall chemical reaction is equal to the sum of the energy changes in the individual reactions comprising it
  7. 9. any substance that increases the rate of a reaction without itself being consumed
  8. 10. a substance which slows downprevents a particular chemical reaction or other process or which reduces the activity of a particular reactant, catalyst, or enzyme
