the reaction shifts to attain equilibrium

If [NOBr] = 1 M [NO] = 0.2 M and [Br2] = 0.8 M calculate the reaction quotient Qc for the reaction 2NOBr(g) ? 2NO(g) Br2(g) and determine which direction the reaction shifts to attain equilibrium.Which direction does the reaction shift when more NOBr(g) is added the temperature is increased and the overall pressure is decreased?
