which symbol can be used to indicate the pressure at which a chemical reaction is carried out?\no $xrightarrow{25^{circ}c}$\no $xrightarrow{delta}$\no $xrightarrow{2 atm}$\no $xrightarrow{pt}$
Answer
Brief Explanations:
- Analyze each option:
- $25^{\circ}C$ represents temperature, not pressure.
- $\Delta$ is often used to indicate heat or a change in a general - sense in chemical reactions, not pressure.
- $2\ atm$ is a unit of pressure (atmosphere is a unit for pressure), so it can be used to indicate the pressure at which a chemical reaction is carried out.
- $Pt$ represents the element platinum, which is often used as a catalyst in chemical reactions, not pressure.
Answer:
C. 2 atm
