It’s the Law!
Tells us that the product of a gas’s volume and pressure is always the same
Boyle’s Law
_______ Boyle
Robert
To react, chemicals must collide with one another so that _________ can be either transferred or rearranged
Electrons
The force per unit area exerted on an object
Pressure
Energy that is stored
Potential
When a gas’s temperature was raised (in a constant pressure), the volume occupied by the gas increased, as well
Charles’s Law
_______ Charles
Jacques
Why does increasing the temperature in a chemical reaction increase the reaction rate?
Molecules move faster, increasing the chances of collision
Name a unit of pressure
(kPa, atm, mm Hg, torr)
Energy that is in motion
Kinetic
This law combines Boyle’s Law and Charles’s Law
The combined gas law
_______ Dalton
John
Why does decreasing the concentration in a solution decrease the reaction rate?
There are fewer reactant molecules to collide with
This device measures the pressure of gasses in our atmosphere
Barometer
What is the 1st Law of Thermodynamics?
Energy cannot be created or destroyed; it can only change forms
When 2 or more ideal gasses are mixed together, the total pressure of the mixture is equal to the sum of the pressures of each individual gas
Dalton’s Law of partial pressures
_______ Joule
James
Besides temperature and concentration of a solution, what is another way to increase/decrease reaction rate that we’ve learned?
Increasing surface area
At a constant pressure, when the temperature of a gas decreases, what happens to its volume?
It decreases
In the metric system, energy is measured in this unit
The Joule
PV = nRT (where P is pressure of gas, V is volume, T is temp, and n is # of moles of the gas, R is a constant) is the equation for which law?
The ideal gas law
_______ Hess
Henri
Chemical reactions never actually finish, but rather they just ___________
Get slower and slower
The pressure exerted by the vapor that sits on top of any liquid
Vapor Pressure
A change in this is the energy change that accompanies a chemical reaction
Enthalpy
States that enthalpy is a state of function
Hess’s law
_______ Pascal
Blaise
These speed up reaction rate without getting used up in the reaction
Catalysts
The pressure of an ideal gas depends on this characteristic
The quantity of the gas
The measure of the disorder that exists in any system
Entropy
