Question

Given

The standard heat of the combustion reaction of liquid n-hexane to form CO2(g) and H2O(l), with all reactants and products at 77°F and 1 atm, is = –1.791 x 106 Btu. The heat of vaporization of hexane at 77°F is 13,550 Btu/lb-mole and that of water is 18,934 Btu/lb-mole.

Physical Property Tables

 

If Q= delta H for the contents of the reactor, at what rate in Btu/s is heat absorbed or released (state which) if 157.0 lbm/s of O2 is consumed in the combustion of hexane vapor, water vapor is the product, and the reactants and products are all at 77°F?

Then Q  = ?
(a signed number) x 106 Btu/s.

Therefore,

=_____?

x 106 Btu/s (a positive number)______? is by the reactor.
