7) If the equilibrium constant (Keq) equals 4.00x1012 for the following reaction between strontium and magnesium:Sr(s) + Mg2+(aq)<==> Sr2+(aq) + Mg(s)Calculate Eo for a strontium=magnesium battery. Enter in volts.

Question

7) If the equilibrium constant (Keq) equals 4.00x1012 for the following reaction between strontium and magnesium:

Sr(s) + Mg2+(aq)<==> Sr2+(aq) + Mg(s)

Calculate Eo for a strontium=magnesium battery. Enter in volts.

Step 1

This problem can be solved using Nernst equation.

Step 2

Given equilibrium constant is 4.00 x 1012

For equilibrium reaction, the Nernst equation can be written as,

Step 3

“n” is the moles of electrons = 2

Keq is the equilibrium constant = 4.00 x 1012

Substitution ...
