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?

Determine the reactants and reaction conditions in the correct order to complete the next conversion.
A certain one-step reaction has an activation energy that is higher for the forward reaction compared to the reverse reaction (choose one): A. Since the reaction is exothermic, the reactant energy is lower than the product energy and thus the energy difference from reactant to transition state is greater than that from product to transition state. B. Since the reaction is exothermic, the product energy is lower than the reactant energy and thus the energy difference from product to transition state is greater than that from reactant to transition state. C. Since the reaction is endothermic, the product energy is lower than the reactant energy and thus the energy difference from product to transition state is greater than that from reactant to transition state. D. Since the reaction is endothermic, the reactant energy is lower than the product energy and thus the energy difference from reactant to transition state is greater than that from product to transition state.
