The reaction X`to` Products
follows first order kinetics. In 40 minutes, the concentration of X changes from 0.1 M to 0.025M. The rate of reaction when concentration of X is 0.01 M is:
A. `1.73 xx 10^(-4) M min^(-1)`
B. `3.47 xx 10^(-5) M min^(-1)`
C. `3.47 xx 10^(-4) M min^(-1)`
D. `1.73 xx 10^(-5) M min^(-1)`

Correct Answer - C
c) k = `(2.303)/t log a/(a-x)`
`=(2.303)/(40 "min") log (0.1M)/(0.025M)`
`(2.303)/(40"min") xx log4 = (2.303 xx 0.6021)/(40"min")`
`=0.03467min^(-1)`
Rate = k[x]
=`(0.03467 min^(-1)) xx (0.01M)`
`3.47 xx 10^(-4) M min^(-1)`
