Question

The rate law for the reaction, NO2 (g) + CO (g) ? NO (g) + CO2 (g), is rate = k [NO2]2. If some carbon monoxide is added to the reaction system, which of the following would be true? (Assume the temperature and pressure of the reaction system remain constant.)

Question options:

Both the reaction rate and k would decrease.

Both the reaction rate and k would remain the same.

Both the reaction rate and k would increase.

The reaction rate would increase but k would remain the same.

The reaction rate would remain the same but k would increase.

Please explain answer

1)

Both the reaction rate and k would decrease.

2)

Both the reaction rate and k would remain the same.

3)

Both the reaction rate and k would increase.

4)

The reaction rate would increase but k would remain the same.

5)

The reaction rate would remain the same but k would increase.

Explanation / Answer

2) Both the reaction rate and k would remain the same.

Because both are independent of concentration of Carbon monooxide
