The effluent at 470 degrees from a coil coater oven contains 3000 ppm total hydrocarbons 390 ppm CO, and 320 ppm methane. After being heated in a afterburner to 1230*F, the effluent gas contains 185 ppm total HC, 790 ppm CO, and 140ppm methane. Determine the conversion effeciency (a) based on total HCs alone, (b) based on total HCs and CO, and (c) based on reactive HCs (excluding methane) and CO

please help! will vote if helpful and correct!
