Can any1 please help me with this redox equn:

An acidified solution of dichromate ions is reduced to chromium (III) ions by sulfur dioxide, which in turn is oxidised to sulfate ions.

If any1 could post the Redox half equn + the oxidation half equn and mabey the total equn it would really help.

I am failling to see the reduction half equn, especially with the no. of electrons.

Thxs
