Fluorine reacts with oxygen to yield oxygen difluoride.
2 F2(g) + O2(g) 2 OF2(g)
What is the value of K if the following concentrations are found at equilibrium: [O2] = 0.200 mol/L, [F2] = 0.0100 mol/L, and [OF2] = 0.0633 mol/L
See my response above about arrows.
K = (OF2)^2/(O2)(F2)^2
Substitute and solve for K.
