Solution: Calculate the equilibrium constant for each of the reactions at 25°C. Express your answer using two significant figures. a. 2Fe3+(aq) + 3Sn(s) → 2Fe(s) + 3Sn 2+(aq) b. O2(g) + 2H2O(l) + 2Cu(s) → 4OH−(

Problem

Calculate the equilibrium constant for each of the reactions at 25°C. Express your answer using two significant figures. 

a. 2Fe3+(aq) + 3Sn(s) → 2Fe(s) + 3Sn 2+(aq) 

b. O2(g) + 2H2O(l) + 2Cu(s) → 4OH(aq) + 2Cu2+(aq) 

c. 2Cr3+(aq) + 3Ni(s) → 2Cr(s) + 3Ni 2+(aq)
