The given graph is a representation of kinetics of a reaction. The y and x axes for zero and first order reactions, respectively are
Options
- Azero order ( y = concentration and x = time), first order ( y = rate constant and x = concentration)
- Bzero order ( y = rate and x = concentration), first order ( y = t 1 2 and x = concentration)
- Czero order ( y = rate and x = concentration), first order ( y = rate and x = t 1 2
- Dzero order ( y = concentration and x = time), first order ( y = t 1 2 and x = concentration)
Correct answer
B. zero order ( y = rate and x = concentration), first order ( y = t 1 2 and x = concentration)
Step-by-step solution
In zero order, rate is independent of Concentration of reactants Rate = K In first order, half life t 1 2 is dependent only on K t 1 2 = 0 . 693 K So no change with respect to concentration.
