AP Chemistry Thou Shalt Not Forget

Front

What does a large K_eq indicate about the equilibrium state of a reaction?

Back

A large K_eq means that there are more products at equilibrium.

Front

Which graph is linear for a first order reaction?

Back

ln[A] vs time is linear for a first order reaction.

Front

What type of mixture are gas mixtures considered due to the random motion of particles?

Back

Gas mixtures are homogeneous.

Front

Under what conditions do real gases behave most like ideal gases?

Back

Real gases behave most like ideal gases at high temperature and low pressure.

Front

In the equation P_total = P_dry gas + P_water vapor, what does P_dry gas represent?

Back

P_dry gas is the pressure of the dry gas collected.

Front

Define equilibrium in the context of chemical reactions.

Back

Equilibrium is the state in which the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

Front

What is the significance of the Arrhenius equation in chemistry?

Back

The Arrhenius equation relates the rate constant of a reaction to temperature and activation energy, showing how temperature affects reaction rates.

Front

What is the difference between a homogeneous and heterogeneous mixture?

Back

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has distinct, separate phases.

Front

Explain the concept of partial pressure in gas mixtures.

Back

Partial pressure is the pressure that a single gas in a mixture would exert if it occupied the entire volume alone.

Front

What is the ideal gas law equation?

Back

The ideal gas law is represented as PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
