Across
- 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
- 5. a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously
- 11. the branch of physical chemistry that is concerned with understanding the rates of chemical reactions.
- 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.
- 13. reaction in which products are produced from reactants and it goes from left to right in a reversible reaction
Down
- 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. any chemical reaction that absorbs heat from its environment
- 4. the movement of one or more components of a mixture to improve contact
- 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
- 7. he average kinetic energy of all the atoms or molecules of that substance
- 8. he energy change in an overall chemical reaction is equal to the sum of the energy changes in the individual reactions comprising it
- 9. any substance that increases the rate of a reaction without itself being consumed
- 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
