  • Chemistry Help?

    1.) Consider the reaction, Cl2 + H2S => 2 HCl + S, which is found to be first order in Cl2. Which step of the proposed mechanism must be slow in order to agree with this rate law?

    Cl2 => Cl+ + Cl-

    Cl- + H2S => HCl + HS-

    Cl+ + HS- => HCl + S

    A) Either 2 or 3 B) only 3 C) 1 D) only 2

    2.) The proposed mechanism for a reaction is

    O3 => O2 + O Slow

    O + NO => NO2 Fast

    Which of the following would be a rate law for the reaction?

    1.

    rate = k[NO][O3]

    2.

    rate = k[NO][O]

    3.

    rate = k[O][O2]

    4.

    rate = k[NO2][O2]

    5.

    rate = k[O3]

    Pls help thank you!!
