Chemistry

where R=8.314 J/(mol⋅K), T is the Kelvintemperature, n is the number of moles of electronstransferred in the reaction, and F=96,485 C/mol e−.

At 68.0 ∘C , what is the maximum value of the reaction quotient,Q, needed to produce a non-negative E value forthe reaction

SO42−(aq)+4H+(aq)+2Br−(aq)⇌Br2(aq)+SO2(g)+2H2O(l)

In other words, what is Q when E=0 at thistemperature?
