Re: Cell Diagram

The salt bridge serves two related functions. The primary function is to complete the circuit so that charge can flow from one half-cell to the other. The second is to balance the mass by allowing the anion to move to the half-cell where additional cations are being produced

Re: Expansion against constant pressure

when a reaction is has constant pressure it is irreversible. For an irreversible expansion, there is an inequality between the external and internal pressures of the system, and thus one form of volume change (either expansion or contraction) occurs.

Re: Reversible and Irreversible Reactions

energy released by a reversible process can do the maximum amount of work because less of the energy is lost as heat. A process that is done quickly (irreversibly) tends to generate turbulence and friction resulting in heat loss to the surroundings.
