At some temperature, the rate constant for the reaction of the type
`2A rarr` Products
is `0.08 Ms^(-1)`. The time it takes for the concentration of A to drop from `1.50M to 0.30M` is

A

zero order, t= 7.5 sec

B

zero order , t= 15 sec

C

first order, t=22.5 sec

D

first order, t= 7.5 sec

Text Solution

Verified by Experts

The correct Answer is:
B

From the unit of K, the reaction is of zero order.
`k=(C_(0)-C)/t`
`0.08 -(1.5-0.30)/t, t=158`
