Question:

Methane is oxidized with air to produce formaldehyde in a continuous reactor. A competing reaction is the combustion of methane. CH4 (g) + O2---- HCHO (g) + H2O (g)
If methane and air are fed into the reactor at 25 and 100 C, respectively and the reactor leaks 1% of the heat released by the two reactions calculate;
a) The final composition of the products,
b) The final temperature of the products
