How to determine the activation energy for donors/acceptors using the Arrhenius eq.?

I am trying to determine the donor/acceptor activation energy for the semiconductor InGaP with the Arrhenius equation. However it contains only one parameter for the activation energy, which turns out to be around $55$meV when fitted on my measurements. Does that mean that this is the activation energy for both donor and acceptor or how can I discern them?

When I make the approximation based on the hydrogen atom I get 2 very different ionization energies:

$E_c - E_d = 8.7$ meV (donor)

$E_v - E_a = 69.5$ meV (acceptor)

(obtained by modifying the hydrogen energy with $\epsilon_{InGaP} = 11.8 \epsilon_0$ instead of $\epsilon_0$, $m_e^*=0.088 m_e$ and $m_h=0.7 m_e$ instead of $m_e$. Data was found in the NSM archive for $T=300$K)
