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

Question

Br2 (aq) + HCOOH (aq) 🡪 2Br- (aq) + 2H+ (aq) + CO2 (g)
What is the rate at which Br2 (aq) is consumed?

Answer 1

5.50 x 10-4
That's because for every mole of Br2 consumed you have an equal number of moles CO2 formed.
