### K and Q at equilibrium

At equilibrium is K=1? wouldnt that make Estandard 0? But if Q=1 is Q also at equilibrium? Wouldnt that make Erxn=Estandard?

Erxn is Estandard at equilibrium. Q=1 at equilibrium. This checks out mathematically using the equation Estandard=Erxn+rt/nf lnq. if q=1, then lnq=0 and Erxn=Estandard

I'm probably about 50% confident in my claim here but I feel like Q doesn't always have to equal 1 at equilibrium. Doesn't it just have to equal K? And K definitely does not have to equal 1. I'm just a little confused about what the original question is asking.

K is equal to 1 at equilibrium, which would make Ecell 0 because there are no more electrons being transferred in the cell. I'm not sure whether Q is equal to 1 at equilibrium though.

For concentration cells, E° is always 0 V.

Is Q = 1 at equilibrium?
