Chlorine dioxide reacts in basic water to form chlorite and chlorate according to the following chemical equation: 2ClO2(aq) + 2OH–(aq) ClO2–(aq) + ClO3–(aq) + H2O(l). Under a certain set of conditions, the initial rate of disappearance of chlorine dioxide was determined to be 2.30 x 10–1 M/s. What is the initial rate of appearance of chlorite ion under those same conditions?

Ancient statues made of marble (a form of calcium carbonate) are damaged by acid rain because the reaction between the sulfuric acid in the rain and calcium carbonate produces soluble calcium sulfate, which washes away: CaCO3(s)+H₂SO4 (aq) CaSO4 (aq)+CO₂(g) +H₂O(1) Suppose an engineer decides to study the rate of this reaction. She prepares four reaction vessels by adding 162.5 g of solid calcium carbonate and 56. mL of 5.0 M sulfuric acid solution to each, and then filling the remainder of the vessel with distilled water. The volume and temperature of each vessel is shown in the table below. Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on. vessel volume temperature B C D 4.0 L 2.0 L 8.0 L 1.0 L 24 °C → 24. °C 24. °C 24 °C…

For the reaction of the ammonium ion with nitrous acid, the net reaction is NH4*(aq) + HNO2(aq) → N2(g) + 2H2O() + H*(aq) If the initial concentration of nitrous acid is 1.00 M and, after 28.8 s has elapsed, the concentration of nitrous acid has fallen to 0.82 M, what is the average rate of the reaction over this time interval? 0.0063 M/s 0.028 M/s -0.0063 M/s -0.028 M/s O 0.063 M/s

Propane combustion results in the production of carbon dioxide and water vapor according to the following balanced chemical equation: C3H8 (g) + 5 O2 (g) --> 3 CO2 (g) + 4 H2O (g) If the concentration of carbon dioxide increases from 0.773 M to 0.961 M in the first 17.2 seconds, what is the rate of reaction (in M/s)? (answer in 3 significant figures)
