Pulley is used to change the direction of a rope or a chain. the actual rotation of the pulley wheel is a side effect, while wheel and axle are used to amplify rotational force. The force can be provided through a rope wrapped around the wheel, but the change of direction is a side effect. hope this helped :)

Answer:
Neither side is favored
Explanation:
In a reaction at equilibrium in which reactants and products are gases, pressure is a factor that produces a shift of the equilibrium position. When the pressure is increased, the equilibrium is shifted to the side of the reaction with a fewer moles. In this reaction:
2 HD(g) ⇀↽ H₂(g) + D₂(g)
There is the same number of moles on both sides:
reactants side: 2 moles HD
products side: 1 mol H₂ + 1 mol D₂ = 2 moles
Therefore, the equilibrium position will not change.
