How would each of the following change the rate of the reaction shown here?

Question

Drag the appropriate items to their respective bins.
Reaction rate increases, reaction rate decreases, or reaction rate doesn’t change
increasing the temperature
adding a catalyst
removing some NO2 (g)
adding 02(g)

Answer 1

increasing the temperature - reaction rate increases
adding a catalyst - reaction rate increases
removing some NO2 (g) - reaction rate decreases
adding O2(g) - reaction rate doesn't change
