  We address the two-dimensional bimolecular annihilation reaction $A + A \to
\emptyset$ in the presence of random impurities. Impurities with sufficiently
long-ranged interaction energies are known to lead to anomalous diffusion,
$<r^2(t)> \sim t^{1-\delta}$, in the absence of reaction. Applying
renormalization group theory to a field theoretic description of this reaction,
we find that this disorder also leads to anomalous kinetics in the long time
limit: $c(t) \sim t^{\delta -1}$. This kinetics results because the disorder
forces the system into the (sub)diffusion controlled regime, in which the
kinetics must become anomalous.
