Which following expression is used to find the corrosion rate from current density of a corroding specimen? b) W/At = c) W/At = d) W/At = and W/At = Correct Answer (I × am) / (n × F)

W/At denotes the corrosion rate, I= current density, am=molecular weight, n=number of electrons transferred, F=faraday constant (96500), d=density of a specimen. is used to calculate the MDD whereas the is used to calculate the MPY.
