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 rate of a certain reaction is given by the following rate law:
rate =k[NO][0,]
Use this information to answer the questions below.
What is the reaction order in NO?
x10
What is the reaction order in 0,?
What is overall reaction order?
At a certain concentration of NO and 02, the initial rate of
M
reaction is 4.0 x 103 M / s. What would the initial rate of the
reaction be if the concentration of NO were halved? Round
S
your answer to 2 significant digits.
The rate of the reaction is measured to be 0.950 M / s when
[NO] = 0.94 M and [O2] =
= 0.58 M. Calculate the value of the
