- 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
