Exothermic reaction moves forward with increase in Temp?

[leumas614]

I did an equilibrium calculation with some chem software that I have and it told me that a syngas reaction

$$CH4+0.5O2\rightarrow 2H_{2}+CO$$

which is an exothermic reaction will proceed to completion at high temperature. If you increase temperature, that should drive the reaction backwards not forwards. I think it has something to do with the fact that there are more moles of products than reactants. Does it have something to do with entropy?

Thanks

Just because reaction is exothermic doesn't mean its equilibrium can't lie far to the right, even in high temperatures. Shift to the left can be very small.
