NEETChemistryChemical KineticsMCQ+4 / −1

The given graph is a representation of kinetics of a reaction

NEET 2022 Phase 1 Chemistry - Chemical Kinetics Question 14 English

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

  1. A
    zero order (y = concentration and x = time), first order (y = t1/2 and x = concentration)
  2. B
    zero order (y = concentration and x = time), first order (y = rate constant and x = concentration)
  3. C
    zero order (y = rate and x = concentration), first order (y = t1/2 and x = concentration)
  4. D
    zero order (y = rate and x = concentration), first order (y = rate and x = t1/2)
View written solutionFree

Correct answer: C

$\bullet$ For zero order reaction

r = k[A]0

r = k (constant)

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

$\bullet$ For first order reaction

$${t_{1/2}} = {{0.693} \over k}$$ (constant)

hence, 'y' as 't1/2' and 'x' as concentration will given desired graph.
