    We study the set of traveling waves in a class of reaction-diffusion equations for the family of potentials $f_m(U)=2U^m(1-U)$. We use perturbation methods and matched asymptotics to derive expansions for the critical wave speed that separates algebraic and exponential traveling wave front solutions for $m\to 2$ and $m\to\infty$. Also, an integral formulation of the problem shows that nonuniform convergence of the generalized equal area rule occurs at the critical wave speed.
