For a chemical reaction A rarr Products,...

For a chemical reaction `A rarr` Products, the rate of disappearance of `A` is given by:
`-(dC_(A))/(dt)=(K_(1)C_(A))/(1+K_(2)C_(A))` At low `C_(A)`, the reaction is of the …. Order with rate constant …..: `("Assume" K_(1), K_(2) "are lesser than" 1)`

A

`I, K_(1)//K_(2)`

B

`I, K_(1)`

C

`II, K_(1)//K_(2)`

D

`II, K_(1)//K_(1)+K_(2)`

Text Solution

Verified by Experts

The correct Answer is:
b
`(-dC_(A))/(dt)=K_(1)(C_(A))/(1+K_(2)C_(A))`
If `C_(A)` is small, `1+K_(2)C_(A)=1`
`:. (-dC_(A))/(dt)=K_(1). C_(A)`

The rate of reaction ((dx)/(dt)) varies with nature, physical state and concentration of reactants, temperature, exposure to light and catalyst, whereas rate constant (K) varies with temperature and catalyst only. The rate constant K is given as K=Ae^(-E_(a)//RT) where A is Arrhenius parameter or pre-exponential factor and E_(a) is energy of activation. The minimum energy required for a reaction is called threshold energy and the additional energy required by reactant molecules to attain threshold energy level is called energy of activation. For a chemical reaction: Ararr Product, the rate of disappearance of A is given by: (-dC_(A))/(dt)=K_(1) (C_(A))/(1+K_(2)C_(A)) . At low C_(A) , the order of reaction and rate constants are respectively:
