Question

the heat of neutralization of NaOH with HCl is 57.3kj and with HCN is 12.1kj .The heat of ionisation of HCN is​

Answer 1

45.3 kJ/mol is the heat of ionisation of HCN.  

Explanation:

• In other words, this is also called enthalpy of HCN.

• The heat of ionisation is defined as the heat a mole needs to make ions.

• Both neutralization and ionisation are terms concerned with thermochemistry.

• Thermochemistry is a subdivision of chemistry that deals with heat produced during a chemical reaction.
