The Great Equilibrium Shift of N2 + 3H2 <=> 2NH3 | "Concentration" - Are you strong enough? | Colligative Properties (Chapter 13) | Chapter 15, Conceptually Thinking | Acid or Base |
---|---|---|---|---|
Mole Fraction
This unit of concentration is determined by dividing the moles of one specific component by the total moles of all components.
|
Boiling-Point Elevation
This colligative property says that the boiling point of a solution (solvent + solute) is higher than that of the pure solvent alone.
|
Equilibrium
This concept or state is in existence when the rate of the forward reaction is equal to the rate of the reverse reaction in a reversible system.
|
Towards the Reactants
This shift is the result of adding NH3 into the system.
|
Acid
A substance that, when dissolved in water, increases the concentration of hydronium cations.
|
Mass Percent
This unit of concentration is determined by dividing the mass of a component in solution by the total mass of the entire solution and then multiplying by 100.
|
Freezing-Point Depression
This colligative property states that the freezing point of a solution (solvent + solute) is lower than that of the pure liquid.
|
Equilibrium Constant
This constant is the numerical value obtained by dividing the (multiplication of the product concentrations) by the (multiplication of the reactant concentrations). It is also dependent on the stoichiometry of the reaction, but not the reaction mechanism
|
Towards the Reactants
This shift is the result of adding heat to this exothermic reaction.
|
Base
A substance that, when dissolved in water, increases the concentration of hydroxide anions.
|
Molarity
This unit of concentration is determined by dividing the moles of solute by the total volume of solution in liters.
|
Quantity or Concentration
Colligative properties are physical properties of a solution dependent on "this" rather than the actual identity of of the solute particles present in a solution.
|
Pressure OR Partial Pressure
Because they can be related by the ideal gas law, the equilibrium constant of a reversible reaction can be calculated by "this" or concentration. The constant in terms of "this" is often denoted K sub p.
|
No Shift (does not change the composition of the equilibrium mixture)
This shift is the result of using a catalyst in this equilibrium system.
|
Base
pH > 7
|
Molality
This unit of concentration is determined by dividing the moles of solute by the mass of solvent in kilograms.
|
Vapor-Pressure Lowering OR Raoult's Law
This colligative property states that the partial pressure exerted by a solvent vapor above a solution is equal to the product of the mole fraction of the solvent and the vapor pressure of the pure solvent itself.
|
Homogeneous
An equilibrium system is known to be "this" when all substances involved are in the same phase.
|
Towards the Products
This shift is the result of reducing the container volume of this equilibrium system but leaving everything else constant.
|
Acid
pH < 7
|
Parts per Million
This unit of concentration is determined by dividing the mass of a component in solution by the total mass of the entire solution and then multiplying by 1000000.
|
Osmosis
This process states that the net movement of solvent through a semipermeable membrane is always toward the solution with the higher solute concentration.
|
Le Chatelier (Le Chaterlier's Principle)
This chemist said "If a system at equilibrium is disturbed by a change in temperature, pressure, or a component concentration, the system will shift its equilibrium position so as to counteract the effect of the disturbance". He even had a principle name
|
Towards the Products
This shift is the result of increasing the pressure in the reaction container by adding non-reactive O2 gas to the equilibrium system.

Acid (carboxilic acid -COOH)
CH3COOH
