which symbol can be used to indicate a chemical reaction that takes place in the presence of a catalyst?\n$xrightarrow{350^{circ}c}$\n$xrightarrow{pt}$\n$xrightarrow{0.5 atm}$\n$xrightarrow{delta}$

Answer

Answer:

B. $\xrightarrow{\text{Pt}}$

Brief Explanations:

In chemical reactions, the symbol above the arrow indicates reaction conditions. Pt (platinum) is a common catalyst. $\xrightarrow{350^{\circ}C}$ indicates temperature - based reaction condition, $\xrightarrow{0.5\ atm}$ indicates pressure - based reaction condition, and $\xrightarrow{\Delta}$ indicates heat as the reaction condition. Only $\xrightarrow{\text{Pt}}$ indicates a reaction in the presence of a catalyst.
