100

The energy change that accompanies a chemical reaction

What is change in enthalpy?

100

Energy will be thought of as a product in the reaction (Heat is released)

Exothermic

100

Increases chemical reaction rate because the reactant molecules (or atoms) move faster, increasing the chance for a collision.

What is higher temperature?

100

The point at which both the forward and reverse actions in a chemical equation have equal reaction rates.

What is chemical equilibrium?

100

1,000 chemistry calories

What is 1 food calorie?

200

A measure of the disorder that exists in any system

What is entropy?

200

Energy will be considered a reactant (heat is absorbed)

Endothermic

200

Doubles for every 10C increase in temperature.

What is the rate of many chemical reactions?

200

What will happen visually over time with forward reaction and reverse reaction?

the two separate lines with merge into one (chemical equilibrium)

200

The maximum amount of solute that can dissolve in a given amount of solvent.

What is solubility?

300

The rate of change of a product in a chemical reaction

What is the reaction rate?

300

Enthalpy is a state function

What is Hess's Law?

300

Decreases the chemical reaction rate because their are fewer reactant molecules (or atoms) to collide with one another.

What is decreasing concentration?

300

The number of chemical reactions that are equilibrium reactions.

What is all?

300

A substance that turns one color in the presence of acids and another color in the presence of bases.

What is an indicator?

400

Catalysts that are in a different phase than the reactants.

What is heterogeneous catalysts?

400

The energy necessary to start a chemical reaction

What is activation energy?

400

Speed up the reaction rate without actually getting used up in the chemical reaction.

What is catalyst?

400

The symbol for the equilibrium constant.

What is K?

400

A reaction that changes a compound into its consituent elements.

What is decomposition reaction?

500

Energy that is transferred as a consequence of temperature differences.

What is heat?

500

The entropy of the universe must always either increase or remain the same. It can never decrease.

What is the second law of thermodynamics?

500

Catalysts that have the same phase as at least one of the reactants.

What is homogeneous catalyst?

500

Can be used as a gauge to tell us where the reaction will end up at equilibrium.

What is the equilibrium constant?

500

The study of matter.

What is chemistry?
