TEXT ANSWER Question 9 Adding earthworms to a compost pile typically increases the rate at which the organic matter in the pile decomposes. A learner wonders whether adding other organisms to the compost pile will have a simi- lar effect on the rate of decomposition. She decides to answer this question by performing an experiment. ● Formulate a valid hypothesis that the learner could test in her experiment. Based on this hypothesis, identify the independent variable and dependent variables for the learner's experiment.

A reaction of the form aAProducts gives a plot of ln[A] versus time (in seconds), which is a straight line with a slope of 7.35 X 103. Assuming [A]0 = 0.0100 M, calculate the time (in seconds) required for the reaction to reach 22.9% completion.
Based on the kinetic theory of matter, what would the action of a catalyst do to a reaction that is the reverse of some reaction that we say is catalyzed?
Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?

Iodomethane (CH3I) is a commonly used reagent in organic chemistry. When used properly, this reagent allows chemists to introduce methyl groups in many different useful applications. The chemical does pose a risk as a carcinogen, possibly owing to iodomethanes ability to react with portions of the DNA strand (if they were to come in contact). Consider the following hypothetical initial rates data: [DNA]0 ( mol/L) [CH3I]0 ( mol/L) Initial Rate (mol/Ls) 0.100 0.100 3.20 104 0.100 0.200 6.40 104 0.200 0.200 1.28 103 Which of the following could be a possible mechanism to explain the initial rate data?
