1) decreasing the temperature is true
2) increasing the pressure (by changing the volume) is false
Explanation: increasing pressure will shift the equilibrium in that direction where the number of moles of gaseous reactants are less. That is in reverse direction so it is false statement.
3) increasing the volume is true
Explanation: Increasing volume will decrease the pressure and shift the equilibrium in that direction where the number of moles of gaseous particles are less and causes forward direction and produces NH3.
4) adding NH4Cl is false
Explanation: NH4Cl is a solid. solids do not participate in euilibrium reactions.
5) adding HCl is false
Explanation: Adding HCl will shift the equilibrium in reverse direction to decrease the increased amount of HCl.
