CORROSION ENGINEERING. PLEASE ANSWER A THRU D ASAP! I WILL LEAVE A GOOD RATING IMMEDIATELY!

Please consider the corrosion of tin (=7.3g/cm3, molar weight =118.71g/mol, e0Sn2+/Sn=0.138V/SHE) in a corrosive solution. The activity of Sn2+ in solution is 103 mol/L at a pH =2. The polarization resistance Rp=0.197mV/A/cm2. The anodic and cathodic Tafel slopes are 0.1V/ decade. The anodic and cathodic current densities are 104 and 105A/cm2, respectively. In order to determine corrosion rates in mpy (mils per year =25.4m/ year): a) Please determine the corrosion potential b) Please determine the corrosion current Icorr considering the anodic and cathodic current densities of 104 and 105A/cm2, respectively. Note: log(icorr)=[Ecellbclog(iH20)+balog(iSn0)/(babc)] c) Please determine the corrosion current Icorr considering a polarization resistance Rp=0.197mV/A/cm2 d) Please determine the corrosion rate in mils per year (mpy)
