- Go to the PhET Reactions and change to Angled shot to see the difference. (a) What happens when the angle of the collision is changed? (b) Explain how this is relevant to rate of reaction.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_forward. Account for the increase in reaction rate brought about by a catalyst.arrow_forward
- 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)Carrow_forward. What does the activation energy for a reaction represent? How is the activation energy related to whether a collision between molecules is successful?arrow_forwardWhich reaction mechanism assumptions are unimportant in describing simple ionic reactions between cations and anions? Why?arrow_forward
- Use the PhET Reactions Single collision" tab of the simulation applet, enable the Energy view by clicking the + icon. Select the first A+BCAB+C reaction] (A is yellow, B is purple, and C is navy blue). Using the straight shot default option, try launching the A atom with varying amounts of energy. What changes when the Total Energy line at launch is below the transition state of the Potential Energy line? Why? What happens when it is above the transition state? Why?arrow_forwardApply collision theory to explain why powdered zinc reacts to form hydrogen gas faster than large pieces of zinc when both are placed in hydrochloric acid solution.arrow_forwardFor the following reaction profile, indicate a. the positions of reactants and products. b. the activation energy. c. E for the reaction.arrow_forward
- . How does the collision model account for the fact that a react ion proceeds faster when the concentrations of the reactants are increased?arrow_forwardWhy awe elementary reactions involving three or more reactants very uncommon?arrow_forwardIn the PhET Reactions under Options. (a) Leave the Initial Temperature at the default setting. Observe the reaction. Is the rate of reaction fast or slow? (b) Click Pause" and then Reset All, and then enter 15 molecules of A and 10 molecules of BC once again. Select Show Bonds" under Options. This time, increase the initial temperature until, on the graph, the total average energy line is completely above the potential energy curve. Describe what happens to the reaction.arrow_forward
