Explanation / Answer

here graph is drawn between ln K   and 1/T

lnK = y -axis

1/T = x - axis

point 1:   x = 4.44 x 10^-3   ,   y = -0.965

point 2 : x = 1.90 x 10^-3   , y = -0.246

rise =   y2-y1 = -0.246 + 0.965 = 0.719

run = x2 - x1 = 1.38 x10^-3 - 3.64 x 10^-3 = - 2.54 x 10^-3

slope = rise / run = - 0.719 / 2.54 x 10^-3 = -283.0

-Ea / R = slop

Ea = 283 x 8.314 = 2353 J / mol = actiavation energy
