Free-energy change, δg∘, is related to cell potential, e∘, by the equationδg∘=−nfe∘where n is the number of moles of electrons transferred and f=96,500c/(mol e−) is the faraday constant. when e∘ is measured in volts, δg∘ must be in joules since 1 j=1 c⋅v.1. calculate the standard free-energy change at 25 ∘c for the following reaction: mg(s)+fe2+(aq)→mg2+(aq)+fe(s)expres s your answer to three significant figures and include the appropriate units.2. calculate the standard cell potential at 25 ∘c for the reactionx(s)+2y+(aq)→x2+(aq)+2y(s)w here δh∘ = -675 kj and δs∘ = -357 j/k .express your answer to three significant figures and include the appropriate units.
