Fe+Ni2+ → Fe2+ +Ni (b) What is the value of E if the concentration of Ni2+ is 4.17 x 10-2 and the concentration of Fe2+ is 5.06 x 10-3? (c) If E = 0.36 V and Ni2+ = 0.10 M, what is the concentration of Fe2+? 6. Given the following equations: (i) 2 D3++ 3 B → 2 D + 3 B2+ (ii) 3 A + D3+→ 3 A+ + D (iii) C + 3 A+ → C3+ + 3 A Arrange the elements A, B, C, and D in order of their activities.
