1. A team of chemists is studying the following equilibrium, which has the given equilibrium constant at a certain temperature:

2 CH4(g) ⇄ C2H2(g) + 3H2(g)

Kp = 2. x 10-7

They fill a reaction vessel at this temperature with 11 atm of methane (CH4) gas.  What is the equilibrium pressure of C2H2?

2. Ammonia decomposes to form nitrogen and hydrogen, like this:

2 NH3(g) ⇄ N2(g) + 3 H2(g)

An industrial chemist studying this reaction fills a 25.0 L tank with 2.2 mol of ammonia gas, and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 2.3 mol.

Calculate the concentration equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.

Round your answer to 2 significant digits in decimal form. (for example: 8.9x102 would be written 890; 8.1x10-2 would be written 0.082)

You mix an equal number of moles of nitrogen gas and hydrogen gas in a rigid container such that the total pressure is 2.0 atm. The gases react at a constant temperature to form ammonia and the system reaches equilibrium according to the equation: N2(g) +3H2(g) = 2NH3(g) a. At equilibrium, the total pressure is 1.7335 at a given temperature. Determine the value of Kp for this reaction at this temperature.

The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium constant, Kp, is calculated from partial pressures instead of concentrations. These two equilibrium constants are related by the equation Kp=Kc(RT)Δn where R=0.08206 L⋅atm/(K⋅mol), T is the absolute temperature, and Δn is the change in the number of moles of gas (sum moles products - sum moles reactants). For example, consider the reaction N2(g)+3H2(g)⇌2NH3(g) for which Δn=2−(1+3)=−2. For the reaction 2A(g)+2B(g)⇌C(g) Kc = 71.6...

For chemical reactions involving ideal gases, the equilibrium constant K can be expressed either in terms of the concentrations of the gases (in M) or as a function of the partial pressures of the gases (in atmospheres). In the latter case, the equilibrium constant is denoted as Kp to distinguish it from the concentration-based equilibrium constant K.
