Nitrogen dioxide is produced from the reaction of nitric oxide and oxygen gases.Calculate the equilibrium constant for the reaction given the equilibrium concentrations at 25 °C: [NO] = 1.08 x 10-7,[O₂] = 0.500,and [NO₂] = 0.100. 2 NO(g)+ O₂(g)  2 NO₂(g)

Quizplus · Accepted Answer

The equilibrium constant expression is:
Keq = [NO₂]²/([NO]²[O₂])
Substitute the given values:
Keq = (0.100)²/[(1.08 x 10^-7)² x 0.500] = 1.71 x 10^12
Therefore, the answer is D.
