Please help!!

Be sure to answer all parts. Determine the overall cell reaction and E degree cell (at 25 degree C) of a Zn electrode in a 1.0 M Zn(NO3)2 solution and a Co electrode in a 1.0 M Co(NO3)2 solution. E degree (Zn2+/Zn) = -0.76 V, E degree(Co2+/Co) = -0.28 V. What reaction occurs in the cell? Zn(s) + 2H+ (aq) rightarrow Zn2+ (aq) + H2(g) Co2+(aq) + Zn(s) rightarrow Co(s) + Zn2+ (aq) Co2+(aq) + Zn2+ (aq) rightarrow Co(s) + Zn(s) Zn2+ (aq) + Co(s) rightarrow Zn(s) + Co2+ (aq) Calculate the E degree cell. E degree cell = V

Explanation / Answer

Zn will get reduced and Co will get oxidised as the reduction potential for Zn2+ is more (-0.76V)

E0 cell = -0.28 - (-0.76) V = 0.48V
