Question

The gas phase reaction between hydrogen and iodine is proposed to occur as follows:

..... step 1 ..... fast: ...... I₂  2 I

..... step 2 ..... slow: .... H₂ + 2 I  2 HI

(1) What is the equation for the overall reaction? Use the smallest integer coefficients possible. If a box is not needed, leave it blank.

+

+

(2)

Which species acts as a catalyst? Enter formula. If none, leave box blank:

(3)

Which species acts as a reaction intermediate? Enter formula. If none, leave box blank:

(4) Complete the rate law for the overall reaction that is consistent with this mechanism.

Use the form k[A]^m[B]ⁿ , where '1' is understood (so don't write it if it's a '1') for m, n etc.

Rate =

Answer 1

The answer(s) to this are the same as to your previous question with the exception that there is no catalyst.
