3.   the substance B is a catalyst for the reaction

4.   the rate-determining step involves collision of three separate molecules

5. the rate law for the reaction will be of the form rate = k[A][B][C]

  • A. 3 and 5 only

  • B. 1 and 5 only
  • C. 2, 3 and 4 only
  • D. 2 and 3 only
  • E. 1, 2 and 4 only
