This is what reaction rates measure
What is the speed of a chemical reaction

Rates are always expressed as these 'optimistic' quantities
What is a positive quantity
200
Chemical reactions proceed faster if what of the reactants is increased
What is the concentration
200
Rate=k represents reactions that don't depend on the concentration of any species, but proceed at a characteristic rate. These reactions are of what order.
What is a first order reaction
200
Each elementary step of a mechanism has a certain molecularity, the number of molecular bits that must what within that step.
What is collide
200

The moles of oxygen atoms in 0.25 moles of Ca3(PO4)2.

What is 2 moles (of oxygen atoms)?

300
Rates of reactions are expressed as the change in the amount of these per unit time
What are reactants or products
300
An increase of what causes molecules to move more rapidly in a reaction
What is an increase of temperature
300
Rate=k[A] represents a reaction that depends linearly on the concentration of a single species. These reactions are known as what order?
What is a first-order reaction
300
A mechanism are exactly what type of details by which a reaction takes place

What is doubled?

400
The most common unit used for a reaction rate
What is molarity per second
400
Increasing the surface area of the reactants increases the rate of the reactions by doing what
What is increasing the amount of collisions in the reactions
400
Rate laws are equations that relate the rate of a reaction to the what of some species in solutions.
What is the concentration
400
The slowest step determines the overall rate of the reaction also known as the what
What is the rate determining step.
400

The conjugate base for H2SO4.

What is HSO4-?

500
Reactions usually occur most quickly at what point in a reaction
What is the beginning of a reaction
500

This acts by changing the mechanism of the reaction

What is a catalyst?

500
In the reaction rate=k[reactant A]^m[reactant B]^n, if m is greater than n, then the change in the concentration of A affects the rate what than the changing concentration of B.
