Citric acid is often used as an acidity regulator in hot water canning of tomatoes. at 25°c it has kat 7.4x10- and a. hº = +4.1 kl/mol for the acid dissociation process. what is the value of the kat of citric acid at 100°c? к тс о

The rate constant at T = 100 C is 1.0*10⁻³

Explanation:

The Arrhenius equation relates two rate constants K1 and K2 measured at temperatures T1 and T2 as shown below:

here, ΔHrxn = standard enthalpy change of the reaction

R = gas constant

From the given information:

K1 = 7.4*10^-4

T1 = 25 C = 25+273 = 298 K

T2 = 100 C = 100+273 = 373K

ΔH°=4.1kJ/mol

K2 = 1.03*10⁻³

m=9
