Integrated Rate Laws: Change in Concentration
with Reaction Time
Consider a general first order reaction: A B
rate = - D[A]/Dt = k[A]
Upon integration over time, we obtain:
ln ([A]0/[A]t) = kt
ln = natural logarithm
[A]0 = concentration of A at t = 0
[A]t = concentration of A at any time t
ln [A]0 - ln [A]t = kt
