We’re given the balanced reaction:

5 Br- (aq) + BrO3- (aq) + 6 H+ (aq) → 3 Br2 (aq) + 3 H2O (l)

We’re being asked to calculate the average rate of consumption of H+ during the same time interval given that the average rate of consumption of Br- is 1.06x10-4 M/s over the first two minutes. Recall that the average rate of a reaction is given by:

where Δ[A] = change in concentration of reactants or products (in mol/L or M) and Δtime = change in time. We can simply do a rate-to-rate comparison based on the stoichiometric coefficients.
