Answer : The rate of NO formation is, 1 M/s
Explanation :
The general rate of reaction is,
Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.
The expression for rate of reaction will be :
From this we conclude that,
In the rate of reaction, A and B are the reactants and C and D are the products.
a, b, c and d are the stoichiometric coefficient of A, B, C and D respectively.
The negative sign along with the reactant terms is used simply to show that the concentration of the reactant is decreasing and positive sign along with the product terms is used simply to show that the concentration of the product is increasing.
The given balanced chemical reaction is:
The rate law expression for this reaction will be:
Given:
Initial concentration of = 0.500 M
Final concentration of = 0.450 M
Time taken = 0.100 s
Now we have to calculate the rate of disappearance of
or,
Now we have to calculate the rate of formation of
The relation between rate of and is:
or,
Thus, the rate of NO formation is, 1 M/s
