Combustion Reactions- Thermochemistry

1. A constant-volume tank consists of a mixture of 120 grams of methane (CH4) gas and 600 grams of O2 at 25 degrees C and 200 kPa. The contents of the tank are now ignited, and the methane gas burns completely. If the final temperature is 1200K, determine (a) the final pressure in the tank, (b) the dry analysis of the product stream and (c) the heat transfer during the process. Please note that no nitrogen participates in this reaction.

2. Determine the highest possible temperature that can be obtained when liquid octane (C8H18) at 25 degrees C is burned steadily with air at 25 degrees C.
