By Le Chatlier's principle, if we change any parameters of the system, then equilibrium shifts in a direction to cancel that change.
A. Addition of HBr, increases the concentration of H2&Br2 by shifting the equilibrium towards left.
B. Increasing temperature increases the concentration of HBr, since forward reaction is endothermic reaction
C. Increase in pressure, shift the equilibrium towards less no of moles of molecules. Hence equilibrium shifts towards right side to increase the amount of hbr
D. Decrease in volume, shifts towards less no of moles.
Shifts towards right side to increase the amount of hbr.
E. Addition of Br2: Shifts towards right side to increase the amount of HBr
F. Addition of Ar: Argon is a inert gas which has no effect on equilibrium.
G. Catalyst: Addition of catalyst has no effect on equilibrium.
