The image depicts a chemical reaction involving an esterification process, likely the Fischer esterification, catalyzed by sulfuric acid.
The reaction is indicated to be carried out in the presence of H2SO4 (Sulfuric acid), typically as a catalyst, and with heating (indicated by 't').
The reaction is an esterification where a carboxylic acid (acetic acid) reacts with an alcohol (ethanol) in the presence of an acid catalyst (sulfuric acid) and heat to form an ester (ethyl acetate) and water. This is a reversible reaction.
Overall Reaction:
\[ CH_3COOH + C_2H_5OH + \xrightarrow{H_2SO_4, t} \; CH_3COOC_2H_5 + H_2O \]
