Consider the following reaction at 298K 2Cr + (aq) + Ni (s)-? 2 Cr2+ (aq) + Ni2+ (aq) Which of the following statements are correct? Choose all that apply The reaction is reactant-favored. E cell n = 2 mol electrons Submit Answer Retry Entire Group 7 more group attempts remaining Next

Explanation / Answer

Eocell =Eoxidation +Ereduction =0.23-0.50=-0.27 V

Eocell is negative, hence reaction is reactant favorable and Delta Go=-nFEo= - 2x96500x(-0.27)= +ve

And no of electrons are 2 mol

So, options A, C and E are correct
