04 Question ( point) For the reduction reaction which occurs at high temperatures, the experimentally determined rate lawis: rate kINOP[H.] Here is a proposed mechanism for the reduction of NO by H Elementary Step1: H()+NOE)>NE)+H,O(E) Elementary Step2 N)+NOCE) N,)+OE) Elementary Step3 H)+0G)Hog) 1st attempt d See Periodic Table See Hint Is this a valid mechanism? Choose one or more: D Yes, because the three proposed steps sum to the total reaction. D Yes, because all three proposed steps match the experimentally determined rate law. No, because the three proposed steps do not sum to the total reaction. D No, because the first step does not agree with the experimentally determined rate law. No, because the second step does not agree with the experimentally determined rate law. No, because the third step does not agree with the experimentally determined rate law. Insufficient information is given to determine if this is a reasonable mechanismExplanation / Answer
lets add the reactions
H2 + NO ==== N + H2O
N + NO ==== N2 + O
H2 + O ===== H2O
----------------------------------
H2 + NO + N + NO + H2 + O === N + H2O + N2 + O + H2O
remove species that appear on both sides
2 H2 + 2NO === 2 H2O + N2
rate law will be
k [ H2]2 * [NO]2, the rate of reaction determined is k [ H2] * [NO]2
the mechanism is not valid
so the answer is
no, because first step does not agree
no, because second step does not agree
no, because third step does not agree
*if this answer is helpfuld dont forget to rate it =)
