Question 23 of 30 Sapling Learning Map h Consider this reaction data: If you were going to graphically determine the activation energy of this reaction, what points would you plot? A products Number Number T(K) k (s) 275 0.395 675 10.758 point 1: 11 To avoid rounding errors, use at least 1 three s Number Number figures in all values point 2. m Determine the rise, run, and slope of the line formed by these points. rise run slope Number Number Number What is the activation energy of this reaction?

Explanation / Answer

here graph is drawn between ln K   and 1/T

lnK = y -axis

1/T = x - axis

point 1:   x = 3.64 x 10^-3   ,   y = -0.929

point 2 : x = 1.48 x 10^-3   , y = -0.277

rise =   y2-y1   = 0.652

run = x2 - x1   = - 2.16 x 10^-3

slope = rise / run = - 0.652 / 2.16 x 10^-3 = - 302

-Ea / R = slop

Ea = 302 x 8.314 = 2509.6 J / mol = actiavation energy

actiavation energy = 2.51 x 10^3 J/mol
