Balanced chemical equation is :
It is given that the equation is in equilibrium.
We need to find what will happen if we add more is added .
By Le Chatelier's principle :
Changing the concentration of a chemical will shift the equilibrium to the side that would counter that change in concentration.
It means production of the side where content is added will decrease and concentration on other side will increase .
So , more NO would form .
Therefore, option B. is correct.
Hence, this is the required solution.
The table with the data is in the picture attached.
Answer:
Explanation:
The reaction equation suggests that the law could have this form:
Then, the work is to find the values of the exponents that satisfy the initial rate data.
A first glance shows that for the third and fourth trials the initial rates are the same. Since for these two trials only the initial concentration of substance B changed (A and C were kept equal), you conclude that the reaction rate does not depend on B, and ist exponent (lower b) is 0.
Then, so far you can say:
When you use trials 1 and 2, you get:
Now, you can use trials 1 and 3 to determine the other exponent:
Thus, you have the rate law:
Now, you just use any trial to obtain k. Using trail 1:
Which yields:
