Across
  1. 1. a substance that speeds up a chemical reaction, but is not consumed by the reaction
  2. 4. measure of the degree of randomness as particles move
  3. 5. Products can react to re-form the reactants
  4. 8. If a stress is applied to a system at equilibrium the system shifts in the direction that relieves the stress
  5. 9. qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions
  6. 10. rate of forwarding reaction equals the rate of reverse reaction and the concentrations of products and reactants remain unchanged
Down
  1. 2. the maximum energy point along the reaction path
  2. 3. slows down reaction rate or prevents reaction from happening
  3. 6. change in concentration of a reactant or product per unit of time
  4. 7. the minimum energy that must be input to a chemical system with potential reactants to cause a chemical reaction
