when work is 0

[connie 2C]

how come work is equal to 0 in a reversible system?

[Samuel G Rivera - Discussion 4I]

I don't think that work is necessarily 0 in a reversible, isothermal process. The values that are equal to 0 are delta U (change in internal energy) and delta H (change in ethalpy).

[Bella Townsend]

In a reversible reaction there is more work done than in a irreversible reaction. In a reversible reaction the change in temperature is zero, aka an isothermal reaction.

[Chris Tai 1B]

In a reversible process, work doesn't necessarily have to be 0. If anything, the amount of work that a system can produce in a reversible process is greater than in an irreversible process, because the external pressure is slowly decreasing to a specific value, rather than being constant the entire time, and thus the equation with work using the integral is used instead of the equation w = -PdeltaV.
In a reversible, isothermal process, deltaU = w+q = 0, but this doesn't necessarily mean that work is 0. However, it does mean that work is equal to the opposite of q, or that q = -w.

The values that are equal to zero in a reversible system are only deltaU and deltaH. (They equal each other)

Work can still have some value (nonzero) when the system is reversible.

it isn't necessarily 0 unless its isothermal and reversible
