Which of the following statements about "a reaction rate" is INCORRECT?
the rate of a reaction describes how fast a reaction proceeds over time.
reaction rates may be expressed in terms of any chemical species involved in the reaction.
reaction rate can be written for the disappearance of a reactant or the appearance of a product.

When combined hydrochloric acid and zinc metal the acid eats away at the metal to produce hydrogen gas and some dissolved metal salts. The rate of this reaction could be measured in terms of the disappearance of the zinc or the rate of appearance of hydrogen gas.
If we were expressing reaction rate in terms of disappearance of zinc metal, we would write:
Reaction rate = - change[zinc]/time
Reaction rate = change[zinc]/time

When combined hydrochloric acid and zinc metal the acid eats away at the metal to produce hydrogen gas and some dissolved metal salts. The rate of this reaction could be measured in terms of the disappearance of the zinc or the rate of appearance of hydrogen gas.
If we were expressing reaction rate in terms of disappearance of zinc metal, we could conclude that following
The slope of the line would be negative, because the concentration of our reactant is constantly decreasing.
The slope of the line would be positive, because the concentration of our reactant is constantly decreasing.
The slope of the line would be negative, because the concentration of our reactant is constantly increasing.

According to collision theory, in order for a chemical reaction to happen there needs to be an effective collision between the reactants. To be effective, a collision must meet the following two requirements:
Molecules collide with enough energy to break bonds
Molecules collide with a favorable orientation
