For a first order reaction (A) toproducts the concentration of A changes from 0.1M to 0.025M in 40 minutes. The rate of reaction of when the concentration of A is 0.01M is:

Answer»

`1.73times10^(-5)M*mi n^(-1)`
`3.47times10^(-4)M*mi n^(-1)`
`3.47times10^(-5)M*mi n^(-1)`
`1.73times10^(-4)M*mi n^(-1)`

SOLUTION :For a FIRST order REACTION `k=(2.303)/(t)"log"(a)/(a-x)=(2.303)/(40)"log"(0.1)/(0.025)=(2.303)/(40)"log"4=(2.303times0.6020)/(40)=3.47times10^(-2) mi n^(-1)`
Rate`=k[A]=3.47times10^(-2)times0.1=3.47times10^(-4)`M/min
