Given that the equilibrium constant for the reaction,
2SO_2(g) + O_2(g) $$\rightleftharpoons$$ 2SO_3(g)
has a value of 278 at a particular temperature. What is the value of the equilibrium constant for the following reaction at the same temperature ?
SO_3(g) $$\rightleftharpoons$$ SO_2(g) + $${1 \over 2}$$ O_2(g)

The value of $$\Delta $$H for the reaction
X_2(g) + 4Y_2(g) $$\rightleftharpoons$$ 2XY_4(g)
is less than zero. Formation of XY_4(g) will be favoured at

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
