The mechanism for the reaction 2H2O2(aq) 2H2O( ) + O2(g) in the presence of I-(aq) is proposed to be: Step 1: H2O2(aq) + I-(aq) H2O(
) + OI-(aq)
(slow)
Step 2: H2O2(aq) + OI-(aq) H2O( ) + O2(g) + I-(aq)
(fast)
What is the molecularity of the rate-determining step?
Independent Variable
A variable that is manipulated or changed in an experiment to determine its effect on the dependent variable.
Room Temperature
A general description of a comfortable indoor environment, typically considered to be around 20°C (68°F) to 22°C (72°F).
Noise Level
The measurement of the ambient level of sound, often referring to the background sound present in a given environment.
Internal Validity
The degree to which a study’s results are attributable to the independent variable, rather than other factors, indicating the study accurately reflects the relationship being tested.
