Question

The decomposition of nitrosyl bromide (NOBr) has an equilibrium constant, Kc, equal to 3.07 x 10-4 at 24oC according to the equation:

2NOBr(g)D 2NO(g) + Br2(g) .

Which of the following system compositions is at equilibrium at 24oC?

( ) [NOBr] = 0.0610M, [NO] = 0.0151M, [Br2] = 0.0108M

( ) [NOBr] = 0.115M, [NO] = 0.0169M, [Br2] = 0.0142M

( ) [NOBr] = 0.181M, [NO] = 0.0123M, [Br2] = 0.0201M

( ) [NOBr] = 0.0450M, [NO] = 0.0105M, [Br2] = 0.0100
