Consider two electrochemical reaqctions. Reaction A results in the transfer of 2 mol of electrons per mole of reactant and generates a current of 5 A on an electrode 2 cm2 in area. Reaction B results in the transfer of 3 mol of electrons per mole of reactant and generates a current of 15 A on an electrode 5 cm2 in area. What are the net reaction rates for reactions A and B (in moles of reactant per square centimeter per second)? Which reaction has the higher net reaction rate?

Reaction A has a higher net reaction rate

Explanation:

Rate of electrochemical reaction rate per unit area =

F = 96500 C ( Faraday constant)

n = number of moles of electrons per mole of reactant

A = Area of electrode

i = current generated

convert the current from Amperes to C

To calculate net reaction of reaction A

i = 5 c

n = 2

A = 2

back to the equation

=  5 / (2 * 96500 * 2) = (1.3 * 10 ^ -5)  mols^-1 cm^-2

To calculate net reaction of reaction B

i = 15 c

n = 3

A = 5

back to the equation

= 15 / ( 3 * 96500 * 5) =  (1.036 * 10 ^ -5)  mols^-1 cm^-2

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.

answer:

a
