The diagram depicts a gas syringe with a piston that can move freely. The syringe holds gaseous hydrogen, gaseous iodine and gaseous hydrogen iodide at equilibrium. $\text{H}_2(g) + \text{I}_2(g) \rightleftharpoons 2\text{HI}(g)$ Three alterations are given. 1 raising the total pressure by introducing an inert gas while the volume remains constant 2 raising the pressure by adding more gaseous hydrogen iodide while the volume remains constant 3 lowering the volume by moving the piston to the left Which alterations will produce an equilibrium position where the rate of the forward reaction is increased?
