29. A mixture of hydrogen and chlorine remains unreacted until it is exposed to ultraviolet light from a burning magnesium strip. Then the following reaction occurs very rapidly.

\( \text{H}_2(g) + \text{Cl}_2(g) \rightarrow 2\text{HCl}(g) \quad \Delta G = -45.54 \text{ kJ}, \Delta H = -44.12 \text{ kJ}, \Delta S = -4.76 \text{ kJ} \),

Select the statement below that best explains this behavior.
(A)The reactants are thermodynamically more stable than the products.
(B)The reaction has a small equilibrium constant.
(C)The ultraviolet light raises the temperature of the system and makes the reaction more favorable.
(D)The negative value for \( \Delta S \) slows down the reaction.
(E)The reaction is spontaneous, but the reactants are kinetically stable.
