Answer 1

Arrhenius equation for the rate constant of the Chemical reaction is given by:- Ka Aiés) . Karate.constant. A = pre-exponential factor. Ea: activation energy of the reaction T= absolute temperature Taking 'in' on both sides, we get. Ink = int. et = hatine (ar) or, Ink = '\nA - Facet Or, 2.303 log k = 2.303 log A - E [lnx=2.303 logus] org logk = logA - I BRT (dividing by 2:303). herie constant = log A. Az preexponential factor is a constant value of . the chemical reaction. thus logA=const.. The equation looks like y=mx te equ for straight Une.. .

Now, if we plot look. Vo (4) diagram, we get a straight line with negative slope. intercept = e = loga Slope = cos BR logk. () → Experimentally, we get informations of a chemical reaction we can measure rate constanta values(k) of a chemical reaction at different temperatures. (T). Plotting log k vs ( diagram, we will get the above diagram from the slope and intercept values (obtained from graph). We can be able to know about the activation energy of the reaction... Islopel = 29.3 R Ea a 2.303R Islopiel ... slopel = pignoring the tive sign to A. Ea = 2.303 x R x Islopel I R=18.314 J K mot s universal gas consta
