He prepares four reaction vessels with 128.7 g of solid carbon and 14.7 g of steam each. Thevolume 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 reasonablyexpect 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.vesselABCDvolume temperature1.0 L2.0 L4.0 L8.0 L260. °℃260. °℃260. °℃260. °Cinitial rate ofreaction????

. Account for the increase in reaction rate brought about by a catalyst.
Define these terms: (a) unimolecular reaction (b) bimolecular reaction (c) elementary reaction (d) overall reaction
How does an increase in temperature affect rate of reaction? Explain this effect in terms of the collision theory of the reaction rate.
use the kineticmolecular theory to explain why an increase in temperature increases reaction rate.
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?
Consider the following activation energy diagram. Which of the following statements about the diagram are true? (a) E a(forward)E a(reverse)(b) B represents the activation energy of the forward reaction. (c) Energy (H)for the reaction is AC. (d) E a(forward)=BA(e) E a(forward)=E a(reverse)C
Why awe elementary reactions involving three or more reactants very uncommon?
Consider the following statements: In general, the rate of a chemical reaction increases a bit at first because it takes a while for the reaction to get warmed up. After that, however, the rate of the reaction decreases because its rate is dependent on the concentrations of the reactants, and these are decreasing. Indicate everything that is correct in these statements, and indicate everything that is incorrect. Correct the incorrect statements and explain.
