  1. 2. the study of the transfer of energy as heat that accompany chemical reactions and physical changes
  2. 4. used to measure the energy absorbed or released as heat in a chemical or physical change
  3. 5. the power to which a reactant concentration is raised is called the (blank) in that reactant
  4. 6. the amount of energy required to raise the temperature of 1g of a substance by 1 degree celsius is the (blank) heat
  5. 9. the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard state is the (blank) enthalpy of formation
  6. 14. absorbs heat
  7. 17. the overall enthalpy change in a reaction is equal to the sum of enthalpy for the individual steps in a process is whose law?
  8. 19. a measure of the average kinetic energy of the particles in a sample of matter
  9. 22. the step-by-step sequence of reactions by which the overall chemical change occurs
  10. 24. species that appear in some steps but not in the net equation
  11. 25. the change in concentration of reactants per unit time as a reaction proceeds is the reaction (blank)
  12. 27. the area of chemistry that is concerned with reaction rates and reaction mechanisms is called chemical (blank)
  13. 28. an equation that relates reaction rate and concentrations of reactants is called the rate (blank) for the reaction
