Kinetics Part 1

For the reaction shown in the previous problem, predict the rate of change in concentration of H2O2 (Δ[H2O2]/Δt) and I3- (Δ[I3-]/Δt) during the same time interval.

• (Δ[H2O2]/Δt)= -0.0044M

  (Δ[I3-]/Δt) = +0.0044 M

• (Δ[H2O2]/Δt)= -0.0088M

  (Δ[I3-]/Δt) = +0.0088 M

• (Δ[H2O2]/Δt)= -0.0044M

  (Δ[I3-]/Δt) = +0.0088 M

• (Δ[H2O2]/Δt)= -0.0088M

  (Δ[I3-]/Δt) = +0.0044 M

What is the relationship between absorbance and concentration?

• they are directly proportional

• they are inversely proportional

• they are not mathematically related

• they are related logarithmically
