Problem

An acidic solution of dichromate is electrolyzed for 8 minutes using 2 A current. As per the following equation Cr2O72−+14H++6e−→2Cr3++7H2O\text{Cr}_2\text{O}_7^{2-} + 14\text{H}^+ + 6\text{e}^- \rightarrow 2\text{Cr}^{3+} + 7\text{H}_2\text{O} The amount of Cr3+\text{Cr}^{3+} obtained was 0.104 g. The efficiency of the process (in %) is ____. Take: F=96000 CF = 96000\text{ C}, atomic mass of chromium = 52
