2NaBr + 2H2SO4 ---> Na2SO4 +Br2 + SO2 + 2H2O
accept ionic equation 2Br- + 2H2SO4 ----> SO4^2- + Br2 + SO2 + 2H2O

I'm confused, the equation I know is 2Br- + H2SO4 + 2H+ ---> Br2 + SO2 +H2O?

There are several "right" answers.

It is possible to form HBr, Br2 and SO2, Br2 and S, even Br2 and H2S,

You will just have to check your spec. and use to equation that they suggest.
