Combustion Reactions- Thermochemistry

A constant-volume tank consists of a mixture of 120 grams of methane gas and 600 grams of O2 at 25*C... If the final temperature is 1200K, determine (a) the final pressure in the tank (b)... (See attachment for full question)

Carnot heat engine

A Carnot heat engine receives heat from a reservoir at 1700 degrees Farenheit at a rate of 700 Btu/min and rejects the waste heat to the ambient air at 80 degrees Farenheit. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at 20 degrees Farenheit and transfers it to the same ambient air at 80 degrees Farenheit. Determine: a) the maximum rate of heat removal from the refrigerated space b) the total rate of heat rejection to the ambient air Answers: a) 4200 Btu/min b) 4900 Btu/min Please show steps. Thanks.
