The following mechanism has been proposed for the reactionof NO with H2 to form N2O and H2O:NO(g) + NO(g)---->N2O2(g)N2O2(g) + H2(g)---->N2O(g) + H2O(g)(a) Show that the elementary reactions of the proposedmechanism add to provide a balanced equation for the reaction.(b) Write a rate law for each elementary reaction inthe mechanism. (c) Identify any intermediates in the mechanism.(d) The observed rate law is rate = k[NO]2[H2]. Ifthe proposed mechanism is correct, what can we concludeabout the relative speeds of the first and second reactions?
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.
The following mechanism has been proposed for the reaction
of NO with H2 to form N2O and H2O:
NO(g) + NO(g)---->N2O2(g)
N2O2(g) + H2(g)---->N2O(g) + H2O(g)
(a) Show that the elementary reactions of the proposed
mechanism add to provide a balanced equation for the reaction.
(b) Write a rate law for each elementary reaction in
the mechanism. (c) Identify any intermediates in the mechanism.
(d) The observed rate law is rate = k[NO]2[H2]. If
the proposed mechanism is correct, what can we conclude
about the relative speeds of the first and second reactions?
