The Fascinating World of Hess Law in A Level Chemistry

As a passionate chemistry enthusiast, I have always been captivated by the concept of Hess Law and its applications in A Level Chemistry. Hess Law, also known as the Law of Constant Heat Summation, is a fundamental principle that allows us to calculate the enthalpy change of a chemical reaction, regardless of the intermediate steps involved. This ingenious law has revolutionized the way chemists approach and understand thermodynamics, making it an essential topic for anyone pursuing their A Level studies in chemistry.

Understanding Hess Law

Hess Law is based on the principle that the enthalpy change of a reaction is independent of the pathway taken. In other words, as long as the initial and final conditions are the same, the overall enthalpy change will remain constant. This means that we can use known enthalpy changes of other reactions to calculate the enthalpy change of a target reaction, by manipulating and combining the given equations. This approach is incredibly powerful, as it allows us to determine the enthalpy change of a reaction that may be difficult to measure directly.

Example Hess Law Action

To illustrate the concept of Hess Law, let`s consider the combustion of carbon to form carbon dioxide:

Equation	Enthalpy Change (ΔH)
C(graphite) + O2(g) → CO2(g)	-393.5 kJ/mol
C(graphite) + O2(g) → CO(g)	-110.5 kJ/mol
2CO(g) + O2(g) → 2CO2(g)	-566.0 kJ/mol

By manipulating and combining these equations, we can determine the enthalpy change for the combustion of carbon:

Equation	Enthalpy Change (ΔH)
C(graphite) + 2O2(g) → 2CO2(g)	-393.5 kJ/mol
2CO(g) + O2(g) → 2CO2(g)	-566.0 kJ/mol
C(graphite) + O2(g) → CO2(g)	-110.5 kJ/mol
C(graphite) + O2(g) → CO(g) + CO(g)	-110.5 kJ/mol + (-110.5 kJ/mol) = -221.0 kJ/mol
ΔH overall reaction:	-393.5 kJ/mol + (-221.0 kJ/mol) + (-566.0 kJ/mol) = -1180.5 kJ/mol

Through this process, we have successfully determined the enthalpy change for the combustion of carbon, using known enthalpy changes from related reactions.
