Question

QUESTION: Write an equation for the following reaction, including AH value.

In a process of making urea, liquid gas, NH3, reacts rapidly with gaseous carbon dioxide, (CO2), to produce solid ammonium carbamate, NH2COONHa. This reversible reaction releases 117 kJ of heat per mole of the carbamate production.

Answer 1

The balanced chemical equation for the reaction is:

NH3(g) + CO2(g) ⇌ NH2COONH4(s)

The AH value for the reaction is -117 kJ/mol.

The equation including the AH value can be written as:

NH3(g) + CO2(g) ⇌ NH2COONH4(s) ΔH = -117 kJ/mol
