Question

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

Moderate
Solution

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=Kaxodxdt=K

x  = K t
↓     ↓ ↓ 
Y    m x

X = Kt
a–(a–x) = Kt
(a–x) = a – K t
    ↓      ↓    ↓  ↓
   Y       c   m  x
