In hypothetical reversible reaction
`underset((1M))(A)underset(t_(1//2)=2"min")overset(t_(1//2)=6.93"min")(hArr)underset((0.4M))(B)`
Forward reaction =1st order
Backward reaction =0 order
What is the rate of disappearance of A at the given moment?

Text Solution

Verified by Experts

The correct Answer is:
0
`(t_(1/2))=6.93` min (1st order `AhArrB(t_(1/1))_(0)=2` min (zero order)
`r=(-d[A])/(dt)=[(0.1)xx(1)^(1)-(0.1)(0.4)^(@)],r=(0.1-0.1)=0impliesr=0`
