In the following redox reaction, Cr_2O_7^ 2- + Fe^ 2+ Fe^ 3+ + Cr^ 3+ , 1 mole of Cr_2O_7^ 2- oxidises

MHT CET Chemistry question

In the following redox reaction, \mathrm{Cr_2O_7^{2-}} + \mathrm{Fe^{2+}} \longrightarrow \mathrm{Fe^{3+}} + \mathrm{Cr^{3+}}, 1 mole of oxidises

Answer: (D)

1 mol accepts 6 mol of electrons (2 Cr: +6 to +3) and each supplies 1, so 6
