A Mixture of Hydrogen and Chlorine Remains Unreacted Until It $\to$

question 111

Multiple Choice

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: H₂(g) + Cl₂(g) $\to$ 2HCl(g)
$\Delta$ G = -45.54 kJ
$\Delta$ H = -44.12 kJ
$\Delta$ S = -4.76 J/K
Which of the following is consistent with this information?

• 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.
