Question

What is the concentration in (a) ppm_{v} and (b) percent
by volume, of carbon monoxide (CO) with a concentration of 103
micrograms/m^{3}? Assume a temperature of 25 degrees
celcius and total pressure of 1 atm.

Answer #1

Based on the "national ambient air quality objectives", the
acceptable hourly average concentration of carbon monoxide (CO) is
35mg/m^3. Find the acceptable concentration of CO in ppm if the
temperature is -30'C and pressure is 0.92 atm. Express the
concentration as a percent by volume.

A tank with a volume of 8.6 ft3 contains 5.36 lbmol of carbon
monoxide (CO) gas at a pressure of 3500 lbf/in.2 Determine the
temperature, in °R. Determine the percent error in temperature of
assuming ideal gas behavior at this state for CO.
Please provide the complete answer.

Carbon monoxide and oxygen are in equilibrium at 1
atm, expressed as: co + 0,5 02 → CO2. The partial pressure for
oxygen is 0,004 atm and for carbon monoxide is 0.008 atm. The
chemical equilibrium constant is assumed to be 0,122.
Determine
a. Partial pressure of CO2
b. Ppm of CO2

The concentration of carbon monoxide in an urban
apartment is 48 micrograms/m^3. What mass of carbon monoxide in
grams is present in a room measuring 10.6 ft x 14.8 ft x 20.5 ft
?

a power plant gas emission contains 17.4% carbon dioxide by
volume. Measurements in the discharge stack indicate a temp of 83.5
°C and pressure of 1 atm.
A) what is the CO2 concentration in unit of ppmv?
B) what is the partial pressure of CO2 In atm?
C) what is the CO2 Concentration in g/m^3?

The molar heat capacity for carbon monoxide at constant volume
is CV,m = 20.17 J/(K·mol). A 13.00-L fixed-volume flask contains
CO(g) at a pressure of 3.00 kPa and a temperature of 25.0 °C.
Assuming that carbon monoxide acts as an ideal gas and that its
heat capacity is constant over the given temperature range,
calculate the change in entropy for the gas when it is heated to
800.0 °C.

What volume of hydrogen gas is produced when
0.685 mol of carbon monoxide
reacts completely according to the following reaction at 0°C and 1
atm?
carbon monoxide ( g )
+ water (
l ) carbon
dioxide ( g ) +
hydrogen ( g
)
=_________ liters of hydrogen gas?

1. The exhaust of an automobile is found
to contain 2% CO, at a temperature of 80°C. Express the
concentration of CO in the exhaust in mg m-3.
2. California’s air quality standard for
nitrogen dioxide (NO2) is 470mg m-3 (at a
temperature of 25°C and 1 atm of pressure). Express the
concentration in ppmv.

CO(g)+Cl2(g)⇌COCl2(g) Carbon monoxide and chlorine gas are
allowed to react in a sealed vessel at 464 ∘C . At equilibrium, the
concentrations were measured and the following results obtained:
Gas Partial Pressure (atm) CO 0.780 Cl2 1.22 COCl2 0.120 What is
the equilibrium constant, Kp, of this reaction? Part B The
following reaction was performed in a sealed vessel at 767 ∘C :
H2(g)+I2(g)⇌2HI(g) Initially, only H2 and I2 were present at
concentrations of [H2]=3.75M and [I2]=2.05M. The equilibrium
concentration...

carbon monoxide is to be burned with air at
atmospheric pressure to produce a gad containing an equal number of
moles of CO and CO2 . The products of combustion leave the furnace
at 4400F. If the only significant reaction is the oxidation of CO
and CO2, what is the composition of the gas leaving the combustion
chamber? You may assume equilibrium at the combustion chamber exit
and the equilibrium at this condition is 6 atm^-1/2.
