What are the equivalence ratio and the percent theoretical air?

A gas turbine burns natural gas (assume methane) where the air is supplied to the combustor at 1000 kPa, 500 K, and the fuel is at 298 K, 1000 kPa. What are the equivalence ratio and the percent theoretical air if the adiabatic flame temperature should be limited to 1800 K?
