- What is the ideal gas law equation?
Show answer
PV = nRT- At STP, what volume does one mole of ideal gas occupy?
Show answer
22.4 L- What does Dalton's Law of Partial Pressures state?
Show answer
Total pressure equals the sum of partial pressures of all gases- At constant temperature and volume, pressure is ____ to the number of moles of gas.
Show answer
directly proportional- How does the volume of a gas change if temperature increases at constant pressure?
Show answer
Volume increases (Charles' Law: V is proportional to T)- What is Graham's Law of Diffusion?
Show answer
The rate of gas diffusion is inversely proportional to the square root of its molar mass- The kinetic energy of gas molecules is directly proportional to ____.
Show answer
absolute temperature- At what condition do real gases deviate most from ideal behavior?
Show answer
At high pressure and low temperature- Define enthalpy (H).
Show answer
A measure of total heat content; H = U + PV, where U is internal energy- A reaction with a negative delta H is ____.
Show answer
exothermic- What does entropy (S) measure?
Show answer
The degree of disorder or randomness in a system- How does entropy change in a spontaneous process?
Show answer
Entropy of the universe increases (Delta S total > 0)- What is Gibbs free energy (G)?
Show answer
G = H - TS; the energy available to do work- A reaction is spontaneous when Delta G is ____.
Show answer
negative- What is the relationship between Delta G and the equilibrium constant (Keq)?
Show answer
Delta G = -RT ln(Keq)
