2 atm is your answer. This is because atm stands for atmosphere which is a unit of pressure.

Answer : The symbol used to indicate the pressure at which a chemical reaction is carried out can be, 2 atm.

Explanation :

Chemical reaction : It is defined as the reaction in which the one or more reactants converted to one or more different substances known as product.

The reactants and product are separated by right arrow.

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.

Some symbols used in the chemical reaction are :

The symbol is used for temperature.

The symbol (s), (l), (g) and (aq) are used for the representation of physical states.

The symbol 'atm' is used for pressure.

Hence, the symbol used to indicate the pressure at which a chemical reaction is carried out can be, 2 atm.
