Correct graphical  representation of  zero order reaction is/are (a = initial concentration; x = amount reacted in time ‘t’)

Rate of reaction is unaffected by change in concentration of reactants in a zero order reaction;Rate remains constant with time;(A) Is correct.dxdt = Ka−xodxdt = Kx  = K t↓     ↓ ↓ Y    m xX = Kta–(a–x) = Kt(a–x) = a – K t    ↓      ↓    ↓  ↓   Y       c   m  x
