... connected the wrong electrode as cathode. This is equivalent to reversing equation (1). When equation (1) is reversed, the measured cell potential difference becomes Eocell = - 1.10 V. The absolute value of ∆Eocell is the same in both cases, but the sign is different. The sign of ∆Eocell is positive ...

... which implies that when dividing ! Qq s, which is not a change of a state variable, by T, which is a state variable, we get a change of the entropy, which we claim to be a state variable. Clearly, this is a claim that needs to be justified. It turns out that to justify this relation we need the seco ...

We know that gases expand spontaneously to fill a container - we know that the opposite does not happen - unless some sort of work is done to b ...
