Be sure to mark which course number you are registered for on your solution. You can turn in the homework online (via Stellar) or in class. Intro to SE Students : Pick any 2 of the 4 problems to solve. SE Students : Pick 3 of the 4 problems to solve. 1. Energy conversion : The combustion of octane takes multiple steps, but these can be condensed as 2C 8 H 18 + 25O 2 16CO 2 + 18H 2 O a. If this process is 100% efficient, how much thermal energy is produced via the combustion of 1 gallon of gasoline? Use the provided enthalpies at the end to support your answer. b. Gasoline consists of octane plus a number of other hydrocarbons. How much thermal energy is produced via combustion of a gallon of gasoline? What component of this comes from combustion of octane? component of this comes from combustion of octane?...
