Reaction conditions

Definition

Reaction conditions refer to the specific parameters under which a chemical reaction takes place, including temperature, pressure, concentration of reactants, and the presence of catalysts or solvents. These conditions play a crucial role in determining the rate and outcome of the reaction, influencing product yield and selectivity. Understanding and controlling reaction conditions is essential for optimizing processes in various fields, particularly in materials science and molecular electronics.
