Problem 78P
Determine whether each redox reaction occurs spontaneously in the forward direction.
(a) Ca2+ (aq) + Zn(s) → Ca(s) + Zn2+ (aq)
(b) 2 Ag+ (aq) + Ni(s) → 2 Ag(s) + Ni2+ (aq)
(c) Fe(s) + Mn2+ (aq) → Fe2+ (aq) + Mn(s)
(d) 2 Al(s) + 3 Pb2+ (aq) → 2 Al3+ (aq) + 3 Pb(s)
Step-by-Step Solution:
Solution 78P :
Step 1:
Here, we have to determine whether each redox reaction occurs spontaneously in the forward direction.
Any half-reaction in the activity series is spontaneous when paired with the reverse of any half-reaction below it and if it’s paired with the reverse of any of any half-reaction above it, then it is nonspontaneous reaction.
