Gases at equilibrium

Ammonium carbamate solid (NH4C02NH2) decomposes at 313 K into ammonia and carbon dioxide gases. At equilibrium, analysis shows that there are 0.0451 atm of C02,0.0961 atm of ammonia, and 0.159 g of ammonium carbamate. 

At a certain temperature, the equilibrium constant for the reaction is 0.0255. What are the partial pressures of all gases at equilibrium if the initial partial pressure of the gases (both reactants and products) is 0.300 atm ... 

The equilibrium constant for the decomposition at a certain temperature is 25. Calculate the partial pressures of all the gases at equilibrium if ammonia with a pressure of 1.00 atm is sealed in a 3.0-L flask. 

If we increase the pressure on a mixture of these four gases at equilibrium, the gases are compressed to a smaller volume. Once again the con-... 

If the total pressure of a mixture of gases at equilibrium is doubled by compression, the equilibrium will shift to the side with fewer moles of gas to counteract the increase in pressure. Thus, if the pressure of an equilibrium mixture of N2(g), H2(g) and NHs(g) is doubled, the reaction involving these three gases, i.e. N2(g) + 3 H2(g) T--2 NHjfg)... 

The Sample Problem on page 344 showed how to calculate the amounts of gases at equilibrium for the following reaction. 

Knowing the value of the equilibrium constant, K, at a given temperature, the composition of a mixture of gases at equilibrium may be calculated as follows. 

The subscript e has been added above to indicate that the pressures in Eq. 9.41 are the pressures of the gases at equilibrium. (Recall from Eq. 9.21 that the pressures in Eq. 9.41 are actually unitless, i.e., the pressures are in units of p°, the standard-state pressure.)... 

A mixture of 1 mol of water vapor and 3 mol of CO is allowed to come to equilibrium at a total pressure of 2 atm. (a) How many moles H2 are present at equilibrium (b) What are the partial pressures of the gases at equilibrium ...

Sample Write the equilibrium constant, Kp, for the following mixture of gases at equilibrium ... 

This principle states that if a system at equilibrium is subjected to a change in conditions, it will respond in a way that counteracts the change. It can be demonstrated by changing the pressure applied to a fixed volume of the following system of gases at equilibrium ... 

Thus, for a system that contains gases at equilibrium, in which the amount (mol) of gas, gas, changes during the reaction (Figure 17.8) ...
