What is the enthalpy of combustion of benzoic acid?
The enthalpy of combustion of benzoic acid ( C 6 H 5 C O O H ) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be -3226.7 kJ/mol.
What is the standard molar enthalpy of combustion per mole of benzoic acid?
The standard enthalpy of combustion of benzoic acid (molar mass 122g/mol ) is −3225kJ/mol.
What is the vapor pressure of benzoic acid?
Benzoic Acid. Vapor pressures of benzoic acid were determined in the temperature range from 310 K to 362 K, corresponding to a pressure range of (0.4 to 69) Pa.
Is benzoic acid an organic compound?
benzoic acid, a white, crystalline organic compound belonging to the family of carboxylic acids, widely used as a food preservative and in the manufacture of various cosmetics, dyes, plastics, and insect repellents.

What happens when benzoic acid is heated?
When benzoic acid is heated in presence of a strong dehydrating agent like P2O5 or H2SO4, it forms benzoic anhydride.
What is the reaction of benzoic acid?
Chemical Reaction Related to Benzoic Acid Benzoic acid has a carboxyl group, which is acidic and so it reacts with a base like sodium hydroxide to produce a salt, sodium benzoate C_6H_5COO^- and Na^+. It is an iron compound and when sodium benzoate is treated with an acid such as HCI and it forms the reactant back.
Is C6H6 O2 → co2 h2o balanced?
The balanced equation is: 2C6H6+15O2→12CO2+6H2O.
What are the 2 products from the complete combustion of benzene?
1 Answer. The products of complete combustion are carbon dioxide and water, as is the case for all organic molecules.
Does benzoic acid decompose when heated?
The three benzoic acid derivatives showed very mild degradation at 150°C. Severe degradation of benzoic acid derivatives was observed at 200°C while their complete degradation occurred at 250°C. However, benzoic acid remained stable at temperatures up to 300°C.
Which product is formed on benzoic acid oxidation?
The primary use of benzoic acid is in the industrial production of the aromatic compound phenol. This is done via a process known as oxidative decarboxylation.
