Answer to Question #102361 in General Chemistry for rates

Question

In the first 15.0 s of the reaction, the concentration of I− drops from 1.000 M to 0.861 M
Predict the rate of change in the concentration of H2O2 (Δ[H2O2]/Δt).

Answer 1

Rate = -(Change of concentration of reactants)/time

= - (0.861-1.00)/15

Rate = 0.0574 M s^-1
