For the reaction, N_2(g) + O_2(g) $$\rightleftharpoons$$ 2NO_(g), the equilibrium constant is K₁. The equilibrium constant is K₂ for the reaction,
2NO_(g) + O_2(g) $$\rightleftharpoons$$ 2NO_2(g)
What is K for the reaction,
NO_2(g) $$\rightleftharpoons$$ $${1 \over 2}$$N_2(g) + O_2(g)

The reaction,
2A_(g) + B_(g) $$\rightleftharpoons$$ 3C_(g) + D_(g)
is begun with the concentrations of A and B both at an initial value of 1.00 M. When equilibrium is reached, the concentration of D is measuread and found to be 0.25 M. The value for the equilibrium constant for this reaction is given by the expression

In which of the following equilibrium K_c and K_p are not equal?

The dissociation constants for acetic acid and HCN at 25^oC are 1.5 $$ \times $$ 10^$$-$$5 and 4.5 $$ \times $$ 10^$$-$$10 respectively. The equilibrium constant for the equilibrium
CN^$$-$$ + CH₃COOH $$\rightleftharpoons$$ HCN + CH₃COO^$$-$$ would be
