Answer» The standard reduction potentials at $298 K$ for the following half reactions are given against each. Which will be the strongest reducing agent,among the following: $Z n^{2 +} (a q) + 2 e^{-} ⇌ Z n (s) - 0.762 C r^{3 +} (a q) + 3 e ⇌ C r (s) - 0.740 2 H^{+} (a q) + 2 e^{-} ⇌ H_{2} (g) 0.00 F e^{3 -} (a q) + e^{-} ⇌ F e^{2 +} (a g) 0.770$
