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

They and x axes for zero and first order reactions, respectively are

zero order (y= concentration and x = time), first order (y = t 1/2 and x =concentration)

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

zero order (y = rate and x = concentration), first order (y = t 1/2 and x = concentration)

zero order (y = rate and x = concentration), first order (y = rate and x = t 1/2 )

Text Solution

Verified by Experts

The correct answer is:

• For zero order reaction, rate is independent of concentration of reactants.

r = k[A]°

r = k (constant)

Therefore, 'y' as 'rate' and 'x' as concentration will give desired graph,

• For first order reaction, t 1/2 is dependent only on K, hence no change with respect to concentration.

(k is constant)

Therefore, 'y' as 't 1/2 ' and 'x' as concentration will give desired graph.
