In the gas phase, iodine reacts with cyclopentene (C₅H₈) by a free radical mechanism to produce cyclopentadiene (C₅H₆) and hydrogen iodide. Explain how each of the following affects the amount of HI(g) present in the equilibrium mixture in the reaction

(a) Raising the temperature of the mixture; 

(b) Introducing more C₅H₆(g) at constant volume; 

(c) Doubling the volume of the container holding the mixture;

(d) Adding an appropriate catalyst;

(e) Adding an inert gas such as He to a constant-volume reaction mixture.
