Question

what are the limitations of the process of sulphuric acid converted into contact process​

Answer 1

hello friend this is your answer

The contact process is the current method of producing sulhuuric acid in the high concentrations needed for industrial processes. Platinum used to be the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulphur feedstock, vanadium(V) oxide (V2O5) is now preferred
