Is change in enthalpy change(of a reaction) dependent on temparature difference alone considering cp  is independent of temparature?if not what are the factors that change, change in enthalpy change

6 years ago


Answers : (1)


Dear nishchith

Yes enthalpy change depends on temperature..

But this effects is counted only at higher temperature...given by Kirchoff equation.

ΔH2-ΔH1=ΔCp ΔT if ΔCp is constant..

ΔCp=(Sum of heat capacities of Products ) - (Sum of heat capacities of Reactant)

if ΔCp is a function of temperature, then the right side will be an integral...put dT in place of ΔT.

other factors are:

Physical state of the reactants and the products



Amount of Reactant
