Question

For the reaction:

\[\ce{2Cl_{(g)} -> Cl2_{(g)}}\]

पर्याय

• ∆H is positive, ∆S is positive

• ∆H is positive, ∆S is negative

• ∆H is negative, ∆S is negative

• ∆H is negative, ∆S is positive

Answer 1

∆H is negative, ∆S is negative

Explanation:

Bond formation is an exothermic reaction that produces heat ∆H is negative. The number of moles in the gaseous product is less than the gaseous reactant. As a result, ∆S is negative.
