How much heat (in kJ/hr) is released/absorbed (specify which) if 100 mol/hr of liquid n-heptane is completely combusted? Assume stoichiometric feed ratio of n-heptane and O2 gas, and that the entering and exiting temperatures of reactants/products remains constant @ 25°C.

Step 1

The combustion reaction of *n*-heptane is:

Step 2

Calculate the standard heat of the reaction and take the data for standard heat of formation for C_{7}H_{16}, O_{2}, H_{2}O, and CO_{2} from the table of standard properties at 25°C as:

Step 3

Now, calculate for the give...
