Gas Laws and Kinetic Molecular Theory
When the volume of a gas decreases at constant temperature, this happens to the pressure.
What is increases?
A reaction that releases energy is called this.
What is exothermic?
In equilibrium, the concentrations of reactants and products remain this.
What is constant?
This number represents the number of particles in one mole.
What is Avogadro's number (or, 6.02 x 1023)?
Compounds containing a carbon-carbon double bond have this ending.
What is -ene?
The correct unit for temperature in gas law equations.
What is Kelvin (K)?
A substance that speeds up a reaction without being consumed is called this.
What is a catalyst?
Adding more C to the equation C + O2 <--> CO2 causes the equilibrium to shift in this way.
What is to the right?
The number of moles of O2 needed to react with 3.4 moles of C in this reaction: C + O2 --> CO2.
What is 3.4 moles?
The prefix used for 8 carbon atoms is this.
What is oct-?
A gas in a smaller container experiences higher pressure because particles do this more often.
What are collisions (with the container walls)?
According to collision theory, reactions occur only when particles collide with enough energy and this.
What is correct orientation?
The principle used to predict equilibrium shifts is called this.
What is Le Châtelier’s Principle?
DAILY DOUBLE: You would need this quantity if you wanted to find the weight of 5 moles of a compound.
What is molar mass?
This is the abbreviation for the element chlorine in a halocarbon.
What is chloro-?
In the ideal gas law equation, this variable represents the number of moles of gas.
What is n?
Decreasing the particle size of a solid increases reaction rate because it increases this.
What is surface area?
In a titration reaction, the moles of these two substances are equal.
What are acid and base?
A solution with more of a solute dissolved in it than should be possible according to the solubility curve can be described in this way.
What is supersaturated?
The name of an 5-carbon compound with a triple bond beginning on carbon 2 is this.
What is 2-pentyne?
When temperature doubles in a container with a fixed volume, this happens to pressure.
What is it doubles?
Entropy is a measure of this quality.
Bromcresol green turns yellow in this type of solution.
What is acidic (or, pH under 3.8)?
A solution where 2 moles of NaCl are dissolved in 1 L of water would have this concentration (including units).
What is 2 M (molar)?
An alkane with 4 carbons would have this many hydrogens.
What is 10?
