The given plots represent the variation of the concentration of a reactant R with time for different reactions (i) and (ii). The respective orders of the reactions are:

A

1,0

B

0,2

C

1,1

D

0,1

Text Solution

Verified by Experts

The correct Answer is:
A
`R rarr P`
a o
`a-x" "x`
For `1^(st)` order reaction
`+(dx)/(dt) =k (a-x)^(1)`

`int (dx)/(a-x) = int k dt`
`-" In "(a-x) =kt +c`
If t=0
C=- In a `therefore -" In "(a-x) =kt -"In "a`
or In (a-x) =-kt+ In a
Y m x c
Similarly
`underset((A))underset((A_(o)))RrarrP`
`(-d[R])/(dt) =k [R]^(o)" or "-d (R) =k dt" or "int d[R] =- int kdt`
`[R] =-kt +c" or "[A] =-kt +c`
y=m x + c
