WebReaction rates were computed for each time interval by dividing the change in concentration by the corresponding time increment, as shown below for the first 6-hour period: −Δ[H2O2] Δt = −(0.500 mol/L−1.000 mol/L) (6.00 h−0.00 h) = 0.0833molL−1h−1. Notice that the reaction rates vary with time, decreasing as the reaction proceeds.
