Solution: Consider two reaction vessels, one containing A and the other containing B, with equal concentrations at t = 0. If both substances decompose by first-order kinetics, wherekA = 4.50 x 10-4 s-1kB = 3.70

Problem

Consider two reaction vessels, one containing A and the other containing B, with equal concentrations at t = 0. If both substances decompose by first-order kinetics, where

kA = 4.50 x 10-4 s-1
kB = 3.70 x 10-3 s-1

how much time must pass to reach a condition such that [A] = 4.00[B]?
