Which of these reactions will proceed spontaneously, based on relative strength of reducing agents? a. Cu (s) + Fe2 (aq) → Cu2+ (aq) + Fe (s) b.
WebAnswer: Cr2+ is a stronger reducing agent than Fe2+. ... Thus Cr2+ is easily oxidised to Cr3+ but Fe2+ cannot be as readily oxidised to Fe3+. How do you determine the best oxidizing agent? The higher the electronegativity the greater the pull an oxidizing agent has for electrons. The higher the pull for electrons the stronger the oxidizing agent. WebOf the options given only Cr3+ fits these criteria. ... The lower on the table the stronger the reducing agent. Of the options given Ca is lowest on the table. Consider the reaction: The oxidation number of C changes by: Select one: a. +2/3 b. -4/3 c. -2/3 d. -2.

So Cr2+ has higher tendency on losing electron compared to Fe2+ so Fe2+ is more stable than Cr2+. Mn2+ has most stable and Co2+ is least stable (least exchange energy due to only 3 unpaired electrons).
