For zero order reaction, a plot of t 1 / 2 versus [ A ] 0 will be

Step-by-step solution

For zero order reaction :- Rate = K conc . 0 [ A ] 0 is the initial concentration and [ A ] t is the concentration after some time. Over the half life, the concentration also becomes [ A ] 0 2 . So, K = [ A ] 0 - [ A ] 0 2 t 1 2 = [ A ] 0 2 t 1 2 So ,   t 1 2 = [ A ] 0 2 k Graph :- Hence, the straight line passing through origin and slope = 1 2 K .
