What quantity of electricity will liberate 0.125 mole of oxygen molecules during the electrolysis of dilute sodium chloride solution?

[ F = 96 5000 C mol^-1 ]

X + Y → Z. The rate equation for the chemical reaction above is ((-Δ[x])/Δt) = K[X]²[Y].

The overall order of the reaction is

When a current I was passed through an electrolyte solution for 40 minutes, a mass X g of a univalent metal was deposited at the cathode. What mass of the metal will be deposited when a current 2I is passed through the solution for 10 minutes?

RS_(aq) + HF_(aq) → RF_(s) + HS_(aq)

ΔH = -65.7 kj mol^(-1).

From the equation above, it can be deduced that
