100

This is how molarity is calculated.

M = mol/L

100

Phases that are included in the equilibrium expression?

What are gas and aqueous

100

4A(g) + 3B(g) <--> 5C(g)

Initially, 10 mol A and 15 mol B are put in a 5L flask.  These are the initial concentrations of A, B, and C.

What is [A] = 2.0M, [B] = 3.0M, [C] = 0.0M

100

This is what determines which way the reaction proceeds when compared to K

What is Q (the reaction quotient)

100

Le Chatlier's Principle states this

What is the direction in which a system will shift to reduce a stress

200

This is used to reduce concentration of a stock solution.

What is a dilution.

200

This/these is/are favored when K < 1?

What is/are the reactant(s)

200

This value changes when initial systems move to equilibrium.

What is mols of reactant(s)

200

When Q = K, the reaction is said to have reached this point

What is equilibrium

200
These are the 4 factors that will shift a system at equilibrium

What are temperature, concentration, volume, and pressure

300

What mass of NaCl is needed to prepare 150 mL of 0.2M solution?

What is 1.75 g?

300

4A (g) + 2B (g) <--> 3C (g)

This is the equilibrium expression for the above equation

What is K = [C]3/[A]4[B]2

300

P2 + 3H2 <--> 2PH3

The above reaction will proceed in which direction when 4 mol P2 and 8 mol H2 are initially added to a 2L flask

What is to the right (products)

300
This is the difference between K and Q

K = equilibrium, Q = initial

300

CO2 + H2O <--> H2CO3

After the system reaches equilibrium, more H2CO3 is added.  The concentration of this/these substance(s) will increase in order to reduce the stress

What are CO2 and H2O

400

How many mols of Ag+ ions are present if 0.65g of AgCl is precipitated from a solution?

0.005 mols Ag

400
The only factor that changes the value of K

What is Temperature

400

H2 + F2 <--> 2HF

Initially, 10 mol H2 and 6 mol F2 are added to a 2L flask.  At equilibrium, 5 mol HF are present.  Draw and fill in the ICE table

ICE, ICE, baby

400

A + B <--> C + D

A 32 L flask has 16 mol of A, B, C, and D.  If K = 58.5, this is the direction in which the reaction shifted to reach equilibrium

What is the right

400

This is what happens to a system at equilibrium when a catalyst is added

Nothing

500

Adding a common ion to a solution will do this to a substance's molar solubility.

What is decrease.
500

An increase in temperature does this to the equilibrium constant of the following reaction

Br2(l) <--> Br2(g)        ΔH > 0

What is increase in value

500

N2 + 3H2 <--> 2NH3

Initially, 12 mol NH3 are put in a 2L flask.  At equilibrium, [N2] = 1.0 M.  This is the value of K

What is 0.59

500

A + 2B <--> 4C + D

Initially, 4 mol of A, B, C, and D are put in a 2L flask.  If K = 4, which direction did the reaction shift in order to reach equilibrium?

What is the system is already at equilibrium under initial conditions

500

5A(g) + 9D(l) <--> 6E(aq) + 3G(g)

This is the direction the system will shift when the volume of the container is increased

What is the left
