A and B should be correct
The answer is
C. Control reaction rate
hope it helps :)
Answer:-
Option 2
Explanation:-
In a multi step reaction, the overall reaction is as fast as the slowest step only.
So the rate of a multistep reaction is the same as the rate of its slowest step.
The gas phase reaction was found to be second order wrt NO2.
So the slowest step must have 2 NO2 since the dependence is second order on NO2.
It was also found to be zero order wrt CO.
So the slowest step must not contain any CO since it’s presence has no effect on the reaction (zero order).
Among all options, only number 2 meets the two criterion
Thus the steps are
NO2 + NO2 – NO3 + NO (Slow)
NO3 + CO – NO2 + CO2 (Fast)
Answer:
substrates
Explanation:
Substrates -
It is one of the biochemical species that is involved in a biochemical reaction , that reacts with the enzyme , in order to give the product , is known as a substrate .
In the very first step , the enzyme selectively binds with the substrate , to give an enzyme - substrate complex .
And , in the last step , complex further gives the final product of the biochemical reaction .
