Q.

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

The y and x axes for zero and first order reactions, respectively, are                [2022]

1 zero order (y = concentration and x = time), first order (y = t1/2 and x = concentration)  
2 zero order (y = concentration and x = time), first order (y = rate constant and x = concentration)  
3 zero order (y = rate and x = concentration), first order (y = t1/2 and x = concentration)  
4 zero order (y = rate and x = concentration), first order (y = rate and x = t1/2)  

Ans.

(3)
