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

`underset(a-x) underset(a) (R) to underset(x)underset(o)(P)`
For `1^(st)` order reaction
`+(dx)/(dt)= k(a-x)^(1)`
`int (dx)/(a-x) = int kdt`
`-ln(a-x)=kt +c `
If `t=0`
`c=-ln a " " :. -ln(a-x)=kt-ln a" or " underset(y)(ln(a-x))=underset(" m x C")(-kt+lna)`

Similarly
`underset((A))underset((A_(0)))(R)to P`
`(-d[R])/(dt)=k[R]^(0) " or " -d(R )=kdt`
or `int d[R] = - int kdt`
`[R]=-kt +c or [A]= -kt +c`
`y=mx +c`
