For the reaction: `X(g) rarr Y(g)+Z(g)`, the following data were obtained at `30^(@)C`:
`{:("Experiment",[X](mol L^(-1)),"Rate" (mol L^(-1) hr^(-1))),(I,0.17,0.05),(II,0.34,0.10),(III,0.68,0.20):}`
In experiment `(I)`, what time will reactant `(X)` take to be reduced into `0.0425 M`?

A

`2.4 hr`

B

`0.48 hr`

C

`3.1 hr`

D

`4.7 hr`

Text Solution

Verified by Experts

The correct Answer is:
D
`a=0.17M, (a-x)= 0.0425M`
`t=(2.3)/(0.294hr^(-1))log.(0.17)/(0.0425)`
`=(2.3)/(0.294)log4(2.3)/(0.294)xx0.6=4.7hr`
