The balanced equation for the reaction of bromate ion with bromide ion in acidic solution is given by: 

BrO-3 + 5Br- + 6H+ --> 3Br2 + 3H2O

At a particular instant in time, the value of -delta[Br-]/delta t is 3.0 x 10-3 mol/L s. What is the value of delta[Br2]/delta t in the same units?

a. 1.8 x 10-3

b. 3.0 x 10-3

c. 5.0 x 10-3

d. 1.5 x 10-3

e. 2.5 x 10-3

Expert Answer

Step 1

Since we know that -delta[Br-]/delta t = rate of disappearance of Br- = 3 X 10-3 

And delta[Br2]/delta t = rate of appearance of Br2 in the reaction.

Since for any reaction the rate of disappearance of reactants and rate of appearance of products in related to there reaction coefficients as 

Rate of disappeara...
