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: CaCO,(s)+H,SO,(aq) Caso (aq)+ CO,(g)+H,0(1) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels by adding 164.7 g of solid calcium carbonate and 75. 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. initial rate of reaction vessel volume temperature 3.0 L 20. °C 1 (highest) 2 2.0 L 22. °C 3. 4 (lowest) 3.0 L 22. °C D. 5.0 L 20. °C

Steady State Model

The steady-state model typically states that the entire universe is always enlarging, although it balances a fixed average density and matter that is being constantly generated to make new galaxies, star forms at a similar rate that the previous ones get indistinguishable due to the growing range and velocity of recession.
