The freezing point of a liquid decreases as a soluble, nonvolatile solute is added
A process is spontaneous if it is accompanied by a decrease in the total entropy of the system and its surroundings
Raising the temperature of an exothermic increases the value of K
Equilibrium is reached when the rate constant of the forward reaction equals the rate constant of the reverse reaction
Increasing the pressure of a reaction by adding an inert gas may change the position of the equilibrium
A Bronsted acid is a Lewis acid, but a Lewis acid is not necessarily a Bronsted acid
Neither the value of K or k change with changing temperature
If the value of K is small, the reaction will be mostly products
If the forces between molecules in a liquid are strong, the vapor pressure of the liquid will be large
Spontaneous processes at constant temperature and pressure are accompanied by a decrease in Gibbs free energy
Standard molar entropies increase with increasing complexity of the substance
The change in Gibbs free energy for a process is equal to the maximum nonexpansion work that the system can do at constant temperature and pressure
Enthalpy is not a state function because its value depends on the path taken to arrive at the current value
The molar heat capacity of an ideal gas at constant pressure is greater than molar heat capacity at constant volume
The enthalpy change for a reverse reaction is simply the negative of the enthalpy change for the forward reaction
Standard reaction enthalpies refer to reactions in which the reactants and products are in their standard states and always at 25C
If change(H) is positive for a reaction, then change(U) will be positive as well, although possibly by a slightly different amount
Flow of current when monochromatic light of sufficientfrequency shines on a plate.
An orbital is described by a set of three ___________ __________
delta S - non isothermal, Cv is independent of temperature
