Explain the following observation in terms of the collision theory, restricting each to about 25 words.

NO(g) + O3(g)--> NO2(g) + O2(g)

(a) An increase in temperature increases the reaction rate.

(b) Compressing the gases into a smaller volume increases the reaction rate.

(c) Adding a small amount of a nickel catalyst to the reaction vessel increases the rate without increasing the temperature.

    a. Increasing T increases the energy of the molecules which increases the probability that a reaction will take place when a collision takes place.

    b. Compressing the gas into a smaller volume increases the concn of the gases and that increases the change of a collision.

    c. Adding a Ni catalyst provides a surface to which the molecules can form an intermediate. It effectively lowers the activation energy for the reaction.

    Did you get the formal charge question taken care of? Do you understand how to assign formal chargers.
