Some graph are sketched for the reactant decomposes in one hour, 20% in two hours, 30% in three hours and so on. The dimensions of the rate constant is:

The order of reaction are respectively.

Options

A. 0,1,2
B. 1,0,2
C. 2,0,1
D. 1,2,0

Answer

B

Explanation

(a)`alpha=1-e^(-kt)`
t=0,`alpha=0implies` and at `t to oo`,`alphato1,implies I^(st)` order
(b) `alpha=(kt)/C_0` for Zero order
`alpha` is directly proportional to 't' so zero order.
( c)`alpha=(C_0kt)/(C_0 kt+1)implies 1/alpha =1+1/((C_0k))1/t` for `II^(nd)` order.
