Multiple Choice

A possible mechanism for the reaction
2NO(g) + O₂(g) $\rightarrow$ 2NO₂(g) is: 2NO(g) →N₂O₂(g)
K₁,k₁',fast
N₂O₂(g) + O₂(g) $\rightarrow$ 2NO₂(g)
K₂,slow
Application of the steady-state approximation gives

• A)[N₂O₂] = 0.
• B)k₁[NO]² -k₂[N₂O₂][O₂] = 0.
• C)[N₂O₂] = (k₁/k₂)[NO]².
• D)k₁[NO]² -k₁'[N₂O₂] - k₂[N₂O₂][O₂] = 0.
• E)[N₂O₂] = (k₁/k₁')[NO]².

Definitions:

Changing Criterion Design

A method of graphing behavioral observations used to evaluate a slow and orderly increase or decrease in a student’s performance level by changing the criterion for the student to receive an intervention in a stepwise fashion.

Target Criterion

A specific goal or standard of performance that individuals aim to achieve in an intervention, training program, or behavioral experiment.

Baseline

The initial set of measurements or observations that serve as a starting point for comparison over time.

Baseline

The initial measurement or conditions against which future changes or improvements are compared in research or interventions.
