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=ΔC_p ΔT if ΔC_{p i}s constant..

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

if ΔC_p 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

Pressure

volume

Amount of Reactant
