q rev

[Emily Lo 1J]

In the equation delta S equals q rev over temperature, what exactly is q rev?

[Tiffany_Chen 2K]

Heat for a reversible equation is qrev. Reversible equations are when the equation is at equilibrium.

'Rev' just means reversible so q rev is used when calculating the heat for a reversible reaction.

When Lavelle uses Rev, it means that the reaction is reversible.

Also notice that this equation can't be used if there is change in V, P, or T, because you have to use one other equations. This also implies reversibility.

When using deltaS = qrev/T to derive the equation for entropy under isothermal and isobaric conditions, work is used in replacementf for qrev. Why is this, and why does the equation end up being positive when work is negative?

[Anna Chen 1K]

q is heat while rev refers to a reversible reaction so q rev is used for calculating heat for a reversible reaction.

[Trent Yamamoto 2J]

Q is the heat released/absorbed and rev refers to the fact that the reaction is reversible

[JesseAuLec1Dis1G]

the subscript rev just signifies that the reaction is reversible.
