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
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:
Pressure
volume
Amount of Reactant
