Print Calculator Periodic Table Question 9 of 12 incorrect x Incorrect Map de Sapling Learning Consider a generic redox reaction x(s)+Y (aq) then suppose that the coefficients in the redox reaction are doubled. How will the following quantities be affected for a voltaic cell under nonstandard conditions? X Doubled Halved Squared No Change Note that n is written as ve orzin some textbooks. InQ Incorrect You are correct that Qwill be squared, but look again at how that will affect InQ. Try comparing in(3) to In(9) or In(5) to In(25).

Explanation / Answer

Doubled - lnQ, n

Squared - Q

No Change - E° , E

Explanation

E =E° - (RT/nF)×lnQ

When coefficient doubled

E = E° - ( RT/2nF)× ln (Q)^2

= E° - (RT/2nF)2lnQ

= E° - ( RT/nF) lnQ
