CHEGG Consider the following reaction: LaTeX: Fe\left(CN\right)_6^{3-}+e^-\longrightarrow Fe\left(CN\right)_6^{4-}F e ( C N ) 6 3 − + e − ⟶ F e ( C N ) 6 4 − From the cyclic voltammetry data, a cathodic peak potential (Epa) of 0.271 V and an anodic peak potential (Epc) of 0.330 V was obtained. Is the reaction reversible?

E°= E°cathode- E° anode= 0.271-0.330= -0.59V

Explanation:

NB: the stoichiometry does not affect E°values,

And the more positive the E° values , the greater it's tendency to become spontaneous and hence irreversible, and the more negative the E° values the more likely to become less spontaneous and reversible, hence the above reaction is reversible

1.73 Molar

Explanation:

The formula is Molarity=moles of solute/liters of solution, which can be written in whatever way you prefer, and examples include: M=N/V or M=mol/L.

M=N/V

M=

Divide 5.63 by 3.25. When you calculate this, you get 1.73, therefore your answer is 1.73 molar.
