Below are sample questions representative of the exercises included on this worksheet and related 11.87 Reaction Rate from Data skill assessments:

Problem 1Difficulty: Mastery

For 3A -> 2B, B is monitored by absorbance with A_abs = 5.00[B]. Absorbance rises from 0.050 to 0.350 in 90 s. What is the average disappearance rate of A?

A0.00100 M/s

B0.000333 M/s

C0.000667 M/s

D0.00300 M/s

Solution & Explanation:ΔA_abs = 0.300, so Δ[B] = 0.300/5.00 = 0.0600 M. B forms at 0.0600/90 = 6.67 x 10^-4 M/s. Reaction rate is half of that, and A disappears at 3 times the reaction rate: 0.00100 M/s.

Problem 2Difficulty: Mastery

A product graph shows [P] = 0.000 M at 0 s, 0.120 M at 20 s, and 0.200 M at 100 s. Which statement about average rate is correct?

AThe average rate must be the same for all intervals.

BThe average rate depends on the interval selected.

CThe 0 s to 100 s rate is larger than the 0 s to 20 s rate.

DThe product is disappearing because the graph curves.

Solution & Explanation:The 0 s to 20 s rate is 0.120/20 = 0.0060 M/s, while the 0 s to 100 s rate is 0.200/100 = 0.0020 M/s. Average rate depends on interval.

Problem 3Difficulty: Mastery

A curved product graph has [P] = 0.080 M at 15 s and [P] = 0.200 M at 45 s. What average formation rate corresponds to the secant line between those points?

A0.0080 M/s

B0.0027 M/s

C0.0040 M/s

D0.0067 M/s

Solution & Explanation:The secant line uses Δ[P]/Δt. Here Δ[P] = 0.200 - 0.080 = 0.120 M and Δt = 30 s, so the average rate is 0.0040 M/s.
