Atoms and molecules move around occasionally ramming into each other. If they do it right, ___

For a collision to be effective, the hit has to be hard enough and it has to be ___

The branch of chemistry that studies how collisions effect the rate of reactions is called ___

Every reaction has a minimum amount of energy required to get it started, this is known as the ___

Where do particles get the energy required to overcome the activation energy?

Just like the cars in a demolition derby, all else being equal, the faster particles move the ___

Under the right conditions nitric oxide reacts with hydrogen gas to produce ___

The speed at which a chemical reaction proceeds is called ___

The reaction rate (the rate at which the concentrations of the reactants decrease) has to be determined ___

The rate law describes the relationship between the initial concentrations of the reactants and ___

The rate law for a reaction equals a constant, k, times the concentrations of ___

In the nitric oxide reaction, doubling the hydrogen doubled the rate so the reaction is ___

In the trials, doubling the nitric oxide caused the rate to increase by eight times, so the reaction is ___

How is the overall order of the rate law obtained?

With respect to the rate law, what is the order of most reactions?

When its forward and reverse rates are equal, a reaction is said to be ___

When calculating the forward and reverse rate laws, notice that the exponents are ___

Often the reverse reaction has such a high activation energy that the collisions are ___

As with any multi-step process, the reaction can only happen as fast as ___

Since it controls how fast everything else can go, the slowest step in a multi-step process is called ___

A chemical that lowers the activation energy of a reaction, thereby speeding it up, is called ___

One of the most common and important classes of catalysts are in living things, and are called ___
