- 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?arrow_forwardMany conditions need to be met to produce a chemical reaction between molecules. What if all collisions between molecules resulted in a chemical reaction? How would life be different?arrow_forward`y 0.30 0.25 0.214 - 0.20 M 0.15 0.10 0.05 500 1000 1500 2000 2500 3000 seconds created Is Br, being created or destroyed by the chemical destroyed reaction? neither created nor destroyed If Br, is being created or destroyed, what is the rate at which it is being created or destroyed 900 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If Br, is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 900 seconds of the reaction?arrow_forward
- A reaction was carried out by mixing 10.00 ml of a 0.60 M solution of blue vegetable dye and 2.50 ml of 0.67 M sodium hypochlorite solution which lasted 45.0 seconds. If the same reaction were carried out using 10.00 ml of the plant dye solution and 5.00 ml of the sodium hypochlorite solution, what would happen more likely? Choose one a. The speed increases. b. The speed decreases. c. The blue color does not disappear. d. The absorbance of the mixture increases.arrow_forwardIn an experiment, sulfuric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was formed during the reaction. A cross drawn at the base of each flask became gradually invisible due the formation of this yellow precipitate. The time taken for the cross to become invisible was recorded. A partial record of the experiment is shown. Based on your knowledge of factors that affect the rates of chemical reactions, predict the trend in the last column of the experimental record. Use complete sentences to explain the trend you predicted. You do not have to determine exact values for time; just describe the trend you would expect (increase or decrease) and why it occursarrow_forwardii) Explain the effect of Catalyst on the rate of a chemical reaction.arrow_forward
