K-L plot can be drawn from LSV for ORR at different rotation rates. first plot your LSV using potential (V) vs current density (mAcm-2). then measure the current density (J) from this plot at particular potential for each LSV, eg. measure current density at -0.2 V for all LSV, then at -0.25 V, -0.28, and so on (you can take 5-10 different potentials). but selection of potential is important, you should select potentials at current density region. Now make a plot between1/J vs 1/w1/2 (w is rotation rate). please follow these papers also...best of luck

You do whatever Mr. Piyush suggest. After the plot between 1/J vs 1/w1/2 (w is rotation rate) you will get the slope and from the slope you will get the number of electron transferred using K-L eqn. Please note that here 'w' in rad/sec.
if you need any help regarding the same, let me know.
