At a certain temperature, the concentrations of NO and NH3 are equal, and the concentration of H2o and o2 are 2.0M and 3.0M respectively. What is the value of Keq at this temp? The equation is 5O2+4NH3-- 4NO+6H20

Question

At a certain temperature, the concentrations of NO and NH3 are equal, and the concentration of H2o and o2 are 2.0M and 3.0M respectively. What is the value of Keq at this temp? The equation is 5O2+4NH3--> 4NO+6H20

DrBob222 · Answer

.......5O2 + 4NH3--> 4NO + 6H20
E........3M....x........x....2M
I assume that this is at equilibrium at this "certain" temperature. Also I assume the "certain" T is high enough that H2O is a gas. If all of that is so then NH3 must be 3M and H2O must be 2M
Plug in the numbers and calculate Keq.
