### Effect of a Catalyst in a Chemical ReactionWhen a catalyst is added to a reaction ...- **A)** ... the rate constant of only the forward reaction is increased.- **B)** ... the rate constants of both the forward and reverse reactions are increased.- **C)** ... the value of the equilibrium constant increases.- **D)** ... the rate constant of only the reverse reaction is increased.In this context, option **B)** is selected, indicating that the rate constants of both forward and reverse reactions are influenced by the addition of a catalyst. This choice correctly reflects the role of a catalyst, which is to speed up both forward and reverse reactions equally without affecting the equilibrium constant.**Explanation:**A catalyst works by providing an alternative reaction pathway with a lower activation energy. This influences both the forward and reverse reactions equally, enhancing the rate constants of both. However, it does not alter the equilibrium position, which means the equilibrium constant remains the same.**Diagram Explanation:**There are no diagrams included in the provided material. Therefore, no further explanation is needed for graphical content.

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?
The equilibrium constant expression for a given reaction depends on how the equilibrium equation is written. Explain the meaning of that statement. You may, if you wish, use the equilibrium equation N2(g)+3H2(g)2NH3(g) to illustrate your explanation.
