- Classify the following processes according to their rates as very slow, slow, or fast: a.The souring of milk stored in a refrigerator b.The cooking of an egg in boiling water c.The rusting of a shovel left in the garden over the winter d.The growing of corn during a warm summer e.The burning of a lighted match.arrow_forwardSubstances 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?arrow_forwardPicturearrow_forward

After 30.0 minutes, 2.55 x 10-3 mol CO, has been generated. Calculate the average rate of the reaction.arrow_forwardCoal gasification produces an easily-transportable, clean-burning combination of carbon monoxide and hydrogen from coal by reacting it with steam, like this: C(s) + H₂O(g) → CO(g) +H₂(g) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels with 95.1 g of solid carbon and 12.3 g of steam 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 4.0 L 2.0 L 4.0 L 2.0 L 300, "C 310, "C 310 °C 330.

Report your answer to the thousandths place and do not include units. 2 MnO4– + 3 CN– + H2O → 2 MnO2 + 3 CNO– + 2 OH–arrow_forwardIron ore is reduced to pure iron by smelting, during which the iron (III) oxide in the ore reacts with carbon monoxide gas, like this: Fe₂O, (s)+3CO(g) 2Fe(s)+3CO₂(g) Suppose an engineer decides to study the rate of this reaction. She prepares four reaction vessels with 153.8 g of solid iron (III) oxide and 9.38 g of carbon monoxide 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 3.0L 1000.

- In a certain chemical reaction, substance A combines with substance B to form substance Y. At the start of the reaction, the quantity of A present is a grams, and the quantity of B present is b grams. Assume a < b and y ≤ a. At time t seconds after the start of the reaction, the quantity of Y present is y grams. For certain types of reactions, the rate of the reaction, in grams/sec, is given by Rate = k(a - y)(b − y), - where k is a positive constant. 1. Sketch a graph of the rate against y. For what values of y is the rate nonnegative? Give your answer as a union of intervals, e.g., (- infinity,-a] U (a, 2b) YE 2. Use your graph to find the value of y at which the rate of the reaction is fastest.
