When carbon dioxide gas dissolves in water, it reacts with the water to form carbonic acid. This is why soft drinks have a low pH, and soda water is often recommended as a mild cleaning agent. It is also why there is concern that rising levels of atmospheric carbon dioxide may cause the Earth's oceans to become more acidic. Here is the reaction between carbon dioxide gas and water: H₂O(1) + CO₂(g) H₂CO3(aq) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels with 152.7 g of water and 34.3 g of carbon dioxide gas each. 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 A B C D 8.0 L 1.0 L 2.0 L 4.0 L 36. °C 36. °C 36. °C 36. °C X initial rate of reaction ? ? ? ✓? 1 (highest) 2 3 4 (lowest)
