Question

For the reaction shown below, the average rate of formation of CO2 (g) is 5.50 x 10-4 mol/L·s:

Br2 (aq) + HCOOH (aq) 🡪 2Br- (aq) + 2H+ (aq) + CO2 (g)

What is the rate at which Br2 (aq) is consumed?

Answer 1

Look at the coeffients. 1 Br2 = 1 CO2; therefore, rate of consumption of Br2 = rate of formation of CO2.
