## The given graph is a representation of kinetics of a reaction.

The y and x axes for zero and first order reactions, respectively are

(1) zero order (y = rate and x = concentration), first order (y = t½ and x = concentration)

(2) zero order (y = rate and x = concentration), first order (y = rate and x = t½)

(3) zero order (y = concentration and x = time), first order (y = t½ and x = concentration)

(4) zero order (y = concentration and x = time), first order (y = rate constant and x = concentration)

**The Correct option is**(1) zero order (y = rate and x = concentration), first order (y = t½ and x = concentration.
