Consider the following reaction N2(g) + 3H2(g) 2NH3(g)0.866 atm of N2 and 0.0496 atm of H2 are placed in a flask; when equilibrium is reached, the pressure of NH3 is 0.0310 atm. Calculate Kpfor the reaction. Use the following steps to solvethis problem:

is 37928.

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

at t= 0     0.866 atm     0.0496 atm        0 atm

At eqm. conc.  (0.866-x) atm   (0.0496-3x) atm        2x atm  

The expression for equilibrium constant for this reaction will be,

given : 2x = 0.0310

x= 0.0155

Now put all the given values in this expression, we get :   

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
