The heat of combustion of liquid toluene (C7H8) is -3910.3 kJ/mol at 1 atm and 298 K.
a) What is the energy of combustion at 1 atm and 298 K?


thanks so much!

warren's class?

answer is -3905.4 kj/mol

you do e = q + h

we know h already. -3910.3

w=-(-ng)(r)(t) -----> (2)(8.314)(298)(1/1000)

then add together.

part b is 12.5 kj/mol

Nah, not yet...i got an orgo test too this week
