what is hesses law please explane with suitable example
Hess' Law states that the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps.Example- A + B = AB, dH1 AB + B = AB2, dH2 then, A + 2 B = AB2, dH1 2 = dH1 + dH2
If a reaction takes place in several steps then its standard reaction enthalphy is sum of standard enthalphy of those intermediate reaction into which ovarLl reaction into which may bedivided at same temperature
Reaction that take place at several steps then its standard reaction enthalphy is the sum of standard enthalphy of those
Hess's Law of Constant Heat Summation (or just Hess's Law) states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes
Hess law states the change of enthalpy of rection in a chemical reaction. It's one example is Methanol.
