### Re: Overall Reaction Enthalpy in Reaction Profiles (15.89)

The overall reaction enthalpy is determined from a reaction profile by looking at the space between the starting state and the final state relative to the y-axis (energy).

### Re: Concept of "Cold"

Adding ice to hot coffee lowers the temperature of the overall substance because the heat from the coffee transfers to the ice therefore "filling" in the absence of heat of the ice resulting in a decrease in temperature of the coffee.

### Re: Reversible vs. Irreversible Process

An irreversible process can be described as a thermodynamic process that leaves equilibrium. In terms of pressure and volume, it occurs when the pressure or volume of a system changes so dramatically that the other pressure or volume in this case, does not have time to catch up. In an irreversible p...
