Liquid phenol at 298 k, 100kPa is burned with 152%
theoretical air at 295k, 100kPa. Determine the adiabatic flame
temperature. Enthalpy of liquid phenol is given as -96,232
kJ/kmol
Octane is burned completely with theoretical air in a
steady-flow process at a constant pressure of 100 kPa. The products
of combustion are cooled to 25 C. Calculate the number of kg of H2O
which will condense per kg of fuel.
200. g of liquid phase octane (C8H18) are burned in air at a
temperature of 100. degrees Celsius and a pressure of 1.00 atm,
forming vapor phase water and carbon dioxide.
a) Write the balanced chemical reaction equation for this
process.
b) What is the magnitude of the difference between ΔE and ΔH for
one mole of octane going through this process? (Hint: use the value
of R that makes life easiest.)
c) The reaction is in contact with a...
Larson (1964) measured the diffusivity of chloroform in air at
298 K and 1 atm and reported its value as 0.093 cm2/s. Estimate the
diffusion coefficient by the Wilke-Lee equation and compare it with
the experimental value.
Calculate the theoretical flame temperature for CO gas burned
at constant pressure with 100% excess air, when the reactants enter
at 100°C.

1. Calculate the adiabatic flame temperature for the following
mixtures initially at 298 K: stoichiometric butane-air mixture,
stoichiometric butane-oxygen mixture, 2.0% (by volume) of butane in
air. Use enthalpies of formation and heat capacities from the NIST
Chemistry WebBook, which can be found at
http://webbook.nist.gov/chemistry/.
2) Repeat the adiabatic flame temperature calculation without the
restriction on the possible products using an online version of the
CEA calculator developed by NASA and located at
http://www.grc.nasa.gov/WWW/CEAWeb/ceaHome.htm. Compare the results
of the two...
