Wild
100
A reaction where energy is located on the product side of a chemical reaction
What is an exothermic reaction?
100

Measure of randomness or disorder in a system

Entropy

100
This stress causes an equilibrium to shift to the side of the reaction with less moles
What is increase in pressure?
100
This is when the rate of the forward reaction is equal to the rate of the reverse reaction.
What is chemical equilibrium?
100

What is the effect of increasing the volume of a closed container equivalent to?

Decreasing the pressure.

200
What are 5 factors that affect the rate of a reaction?
What are pressure, catalyst, temperature, surface area, concentration (or any other legitimate response)?
200

Heat of reaction or delta H

Enthalpy

200
When SO2(g) is removed from 2S02(g) + O2(g) <-- --> 2SO3 the reaction shifts in this direction.
What is left?
200
This is the principle that states a system (rxn) in equilibrium will shift direction to balance any changes that are made.
What is Le Chatelier's Principle
200

A reaction where energy is located on the reactant side of a chemical reaction

Endothermic Reaction

300
What is the effect of a catalyst on the reaction rate?
What is lowers the activation energy, creating a faster pathway for a chemical reaction?
300

Total amount of energy available to do work in a system

Free Energy

300

In the reaction, A + B <--> C + D, What will happen to the equilibrium if excess D is added to the system?

Shift left in order to consume the excess D added and produce more A and B

300
This is a number that relates the concentrations of reactants and products of a reversible chemical rxn at a given temperature.
What is equilibrium constant?
300

When bonds are broken, energy is ________

Absorbed

400

What two conditions are necessary in order for a reaction to occur

Proper energy and proper orientation

400
According to this theory atoms, ions, and molecules can react to form products when they collide with one another
What is collision theory?
400
Direction of the equilibrium shift when temperature is increased in an exothermic reaction.
What is left?
400
This is a reaction that proceeds until one reactant is used up.
What is an irreversible reaction? (not in equilibrium)
400
In the reaction: CuCO3(s) + 2HCl(aq) --> CuCl2(aq) + H2O(g) + CO2(g) powdering CuCO3 does this. (Think Collision Theory)
What is increase surface area and speed up reaction?
500
The minimum energy that colliding particles must have in order to react.
What is activation energy?
500

What is the name for the slowest step in a reaction? (think a string of cars going down the road)

The rate determining step

500
The shift in equilibrium when the pressure is increased on the following reaction: 2SO2(g) + O2(g) <--> 2SO3(g)
What is to the right (products)?
500
Before equilibrium is established, the rate of these will be decreasing.
What are reactants?
500
This states that all matter is made up of particles that are in constant motion because they possess a certain energy
