A mixture of oxygen, hydrogen and nitrogen gases exerts a total pressure of 6.75 atm. If the partial pressures of the oxygen and the hydrogen are 102000 Pa and 751 mmHg respectively , what would be the partial pressure exerted by the nitrogen in atm ?

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
