A certain reaction `A + B rarr` Products is first order w.r.t. each reactant with `k = 5.0 xx 10^(-3) M^(-1) s^(-1)`. Calculate the concentration of `A` remaining after `100s` if the initial concentration of `A` was `0.1 M` and that of `B` was `6.0 M` State any approximation made in obtaining your result.

Explanation

`4.96 xx 10^(-3) M`
