Question

The oxidation-reduction reaction given below has a standard cell potential

E^⁰_cell  = −2.15 V.

3 Sr²⁺(aq) + 2 Cr(s) → 2 Cr³⁺(aq) + 3 Sr(s)

What is the spontaneity of this reaction under standard conditions? There is only ONE submission for this question.

spontaneous

nonspontaneous  

Answer 1

3 Sr²⁺(aq) + 2 Cr(s) → 2 Cr³⁺(aq) + 3 Sr(s)

standard cell potential

E^⁰_cell  = −2.15 V.

delta Go = - n F Eocell

if Eocell is positive , then delta Go is negative . then spontaneous

of Eocell is negative , then delta Go is positive , non - spontaneous

here Eocell is negative. so this is non-spontaneous
