For an elementary reaction , `X(g)toY(g)+Z(g)`
the half life period is 10 min. In what period of time would the concentration of X be reduced to 10% of original concentration?

A

20 min

B

33 min

C

15 min

D

25 min

Text Solution

Verified by Experts

The correct Answer is:
B
`k=(0.693)/(10)=0.0693"min"^(-1)`
`t=(2.303)/(0.0693)log.(100)/(10)=` 33 min
