Multiple Choice

Given the initial rate data for the decomposition reaction, A ? B + C
Determine the rate expression for the reaction.
$$\begin{array} { l l } { [ \mathrm { A } ] , \mathrm { M } } & - \Delta [ \mathrm { A } ] / \Delta t \mathrm { M } / \mathrm { s } \\\hline0.084 & 12.4 \times 10 ^ { - 6 } \\0.063 & 9.3 \times 10 ^ { - 6 } \\0.042 & 6.2 \times 10 ^ { - 6 }\end{array}$$

• A) \(\frac { - \Delta [ \mathrm { A } ] } { \Delta t } = 1.5 \times 10 ^ { - 4 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ]\)
• B) \(\frac { - \Delta [ \mathrm { A } ] } { \Delta t } = 1.5 \times 10 ^ { - 4 } \mathrm { M } ^ { - 1 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] ^ { 2 }\)
• C) \(\frac { - \Delta [ \mathrm { A } ] } { \Delta t } = 1.8 \times 10 ^ { - 9 } \mathrm { M } ^ { - 1 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] ^ { 2 }\)
• D) \(\frac { - \Delta [ \mathrm { A } ] } { \Delta t } = 1.2 \times 10 ^ { - 5 } \mathrm { Ms } ^ { - 1 }\)
• E) \(\frac { - \Delta [ \mathrm { A } ] } { \Delta t } = 6.8 \times 10 ^ { 3 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ]\)

Definitions:

Seasonal Migration

Seasonal migration is the movement of species from one region to another in response to changes in season, often seeking favorable climates, breeding locations, or food sources.

Conditioned Responses

Learned responses to a particular stimulus conditioned through repeated associations with a reinforcement or punishment.

Involuntary Response

A reflex action or response that occurs without conscious control, often as a protective mechanism.

Stimulus

An external factor or signal that triggers a physiological response in an organism.
