Pure sulfur is burned with 63% excess air according to the
following reaction.
S + O2 = SO2 The furnace gases formed enter a reactor under a
pressure of 1 atm at 500 ° C.
80% of SO2 is converted into SO3 by SO2 +1/2 O2 =SO3 reaction.
According to this,
a) Calculate the equilibrium constant Kp of the SO2 +1/2 O2 = SO3
reaction. (10 points)
b) What should be the reactor pressure to increase the conversion
rate of...

A bomb calorimeter, or constant volume calorimeter, is a device
often used to determine the heat of combustion of fuels and the
energy content of foods. Since the "bomb" itself can absorb energy,
a separate experiment is needed to determine the heat capacity of
the calorimeter. This is known as calibrating the calorimeter. In
the laboratory a student burns a 0.466-g sample of 1,8-octanediol
(C8H18O2) in a bomb calorimeter containing 1200. g of water. The
temperature increases from 25.90 °C...

1.A bomb calorimeter, or a constant volume calorimeter, is a
device often used to determine the heat of combustion of fuels and
the energy content of foods. In an experiment, a 0.3807 g sample of
1,6-hexanediol (C6H14O2) is burned completely in a bomb
calorimeter. The calorimeter is surrounded by 1.139×103 g of water.
During the combustion the temperature increases from 25.30 to 27.59
