Select all that apply. O Yes, because the three proposed steps sum to the total reaction. Yes, because all three proposed steps match the experimentally determined rate law. n No. because the three proposed steps d not sum to the total reaction. Check Answer View So O Hint rogress 3 4 5 6 7 8 9 1 11 12

Explanation / Answer

1. 2H2 + 2NO ------------------>2H2O + N2

Yes, because the proposed steps sum to the total reaction.

2. H2 + O -------------------->H2O

Yes, because the three proposed steps sum to the total reaction.
