For the reduction reaction
2no(g)+2h2(g) > n2(g)+2h2o(g)
which occurs at high temperatures, the experimentally determined rate law is: rate = k[no]2[h2]
here is a proposed mechanism for the reduction of no by h2:
elementary step 1: h2(g)+no(g) > n(g)+h2o(g)
elementary step 2: n(g)+no(g) > n2(g)+o(g)
elementary step 3: h2(g)+o(> h2o(g)
is this a valid mechanism?
choose one or more:
a)yes, because the three proposed steps sum to the total reaction.
b)yes, because all three proposed steps match the experimentally determined rate law.
c)no, because the three proposed steps do not sum to the total reaction.
c)no, because the first step does not agree with the experimentally determined rate law.
d)no, because the second step does not agree with the experimentally determined rate law.
e)no, because the third step does not agree with the experimentally determined rate law.
f)insufficient information is given to determine if this is a reasonable mechanism.
