Question

The reversible, gas-phase reaction, 2A->B is in equilibrium in a piston-cylinder at 3.5-bar pressure. At equilibrium, the system contains 2.0 mol A and 3.0 mol B. When 5.0 mol of an inert gas are added to the system, how many moles of B are present at equilibrium? The pressure and temperature do not change. Assume ideal gases.

Answer #1

The gas phase reaction, 2A B C, is carried out in a PFR. The
feed is equal molar in A and B and the entering temperature is 650K
and the entering pressure is 21 atm. If the exit conversion is X,
then the exit concentration of B (in mol/dm3 ) is:

A cylinder sealed with a piston contains an ideal gas. Heat is
added to the gas while the piston remains locked in place until the
absolute temperature of the gas doubles.
1. The pressure of the gas a. doubles b. stays the same c. drops
in half
2. The work done by the surroundings on the gas is a. positive
b. negative c. zero
3. The thermal energy of the gas a. doubles b. stays the same c.

A cylinder if fitted with a floating piston oriented
horizontally (the air is the system and by having a floating piston
it maintains constant pressure). It contains 24.5 L of air at 25.0C
and 1 bar pressure. The system is then heated to 250.0C. Air can be
considered a diatomic gas and therefore would have a Cv = 5R/2,
where R is the ideal gas constant. Also for gases Cp = Cv +R. How
much work was done (in J)...

A gas phase that is at equilibrium with respect to the following
reaction at 500 K contains carbon dioxide, carbon monoxide, and
oxygen.
2CO2(g) → 2CO(g) +
O2(g)
a) Calculate the equilibrium partial pressure of oxygen if the
carbon dioxide partial pressure is 0.20 atm and the carbon monoxide
partial pressure is 0.40 atm. The ∆G°f values for
CO2 and CO at 500 K are -94.389 kcal/mol and -37.140
kcal/mol, respectively.
b) Calculate the total pressure at equilibrium if the...

0.100 moles of He are contained in a piston at equilibrium under
an external pressure of 2.80 atm at 298 K. The external pressure if
reduced to 1.20 atm and the piston is allowed to expand and return
to equilibrium, at the same temperature. How much work is done by
the system? Assume the gas is ideal.

A closed piston-cylinder system contains a 120

m3. It undergoes the following cyclic
process:
A -> B: I
There is isothermal expansion to volume double of the original.
B -> C:
Constant-volume process back to its original pressure .
C -> A:
Constant-pressure process back to its initial state
a) Draw a Pressure volume diagram for the cycle. You

An insulated cylinder is filled with nitrogen gas at 25ºC and
1.00 bar. The nitrogen is then compressed adiabatically with a
constant pressure of 5.00 bar until equilibrium is reached. i. What
is the final temperature of the nitrogen if it is treated as an
ideal gas with molar heat capacity CP = 7/2 R ?
ii. Calculate ΔH (in kJ mol-1 ) and ΔS (in J mol-1 K-1 ) for the
compression. (Hint: Because the enthalpy is a state...

A 7.76-L cylinder contains 1.69 mol of gas A and 4.15 mol of gas
B, at a temperature of 33.3 °C. Calculate the partial pressure of
each gas in the cylinder. Assume ideal gas behavior.
What is the total pressure?

One mole of ethylene at 1 bar and 25C is placed inside a
frictionless piston-cylinder device. The gas is then subjected to a
two-step process: (1) by keeping the piston fixed with a lacking
mechanism, 25KJ of heat is added via an electrical heater; and
(2)the locking mechanism is then released and 15KJ of heat is
removed. The second step of the process takes placed at constant
pressure. Assuming ethylene is an ideal gas, determine the
following:
(a) The temperature...

A cylinder contains 1.5 moles of ideal gas, initially at a
temperature of 113 ∘C. The cylinder is provided with a frictionless
piston, which maintains a constant pressure of 6.4×105Pa on the
gas. The gas is cooled until its temperature has decreased to 27∘C.
For the gas CV = 11.65 J/mol⋅K, and the ideal gas
constant R = 8.314 J/mol⋅K.
