Me choices for blank 1 stabilizes the forward reaction increases the energy decresases the collisions blank 2 remains constant increases decreases

Blank One. Removal of a chemical (reactant) does not stabilize the reaction. If a reactant is removed, the equilibrium has been destroyed. Something has to shift.

Less reactant means that some of the product will have to decompose to make more reactant. Reactant taken out. A product decomposition tries to take it's place.

If the second choice of the first question (increases energy) isn't a determining factor.  The reaction will not get energy out of nowhere.

The obvious answer to this is that if you remove a reactant, you are certainly going to decrease the number of reactants collisions possible

Decreases collisions.

Blank Two: Nothing remains constant once you've upset the equilibrium. If you remove a reactant one of increases or decreases the rate of reaction has to be an answer. The fewer reactants around the slower the reaction. Think marriage. The fewer one gender the less chance of an overpopulate opposite gender will find a mate. Too much competition.

Decreases
