2009 Midterm Question #2 Part C

Postby 704578485 » Sat Feb 06, 2016 12:54 pm

Question #2 part C of the 2009 midterm asks what the change in internal energy is for the combustion reaction of 2 moles of butane. However, it specifies that the reaction occurs at 1atm and 300degrees celcius. The answer to part c is -5.77x10^6J but wouldn't change in internal energy be 0 because the reaction is isothermal at 300 degrees celcius?

combustion release heat and the heat transfer will cause change in internal energy
