### Abstract

We improve the calculation of the equation of state for two flavor QCD by simulating on N_{t} = 6 lattices at appropriate values of the couplings for the deconfinement/chiral symmetry restoration crossover. For am_{q} = 0.0125 the energy density rises rapidly to approximately 1 GeV/fm^{3} just after the crossover(m_{π}/m_{p} ≈ 0.4 at this point). Comparing with our previous result for N_{t} = 4 [1], we find large finite N_{t} corrections as expected from free field theory on finite lattices. We also provide formulae for extracting the speed of sound from the measured quantities.

For amq = 0.0125 the energy density rises rapidly to approximately 1 GeV/fm3 just after the crossover(mπ/mp ≈ 0.4 at this point). Comparing with our previous result for Nt = 4 [1], we find large finite Nt corrections as expected from free field theory on finite lattices.
