The rate constant for a reaction is measured as a function of time.

Question

A plot is created by graphing ln(k) on the y-axis and 1/T on the x-axis, and a best fit line with a slope of -98,535 K is obtained. Based on this data what is the activation energy of this reaction (in kJ/mol)?



R= 8.314 J/(K mol)

Enter your value with three significant figures.

Answer 1

Slope=(-E)/R

E = - R(slope) = - (8.3145 J/K mol)( - 98,535 K)( 1KJ/1000 J)

= 819 KJ/mol
