Given the reaction system;
2 NO (g) + O2 (g) -> 2 NO2 (g)

Write a brief explanation for each of the following statements in terms of the collision model and/or reactions mechanisms.

(1)Increasing the concentration of NO (g)makes the reaction go faster.

(2)Increasing the concentration of O2(g) has no effect on the reaction rate.

(3)Raising the temperature of the reaction mixture greatly increases the reaction rate.
