Question

Transcribed Image Text:Normal heptane n-C,H16 is major component of straight-run
gasoline, which is catalytically isomerized at petroleum
factory to commercial gasoline. Several decades ago, straight-
run gasoline was as fuel in cars.
Calculate its standard enthalpy of reaction of combustion A¸H°
of normal heptane using Data Section of Atkins Book.
Is the calculated numeric value of A̟H° positive, negative or
2)
zero?
Is the calculated numeric value of AH° consistent with the fact
that normal heptane is a fuel?
Make sure to show your calculations in detail.
